89xy+34-x=52

This is a function. It appears you want to convert it into something more manageable. I'll solve it for x and y for you.
Solving For y
89xy+34-x=52
89xy-x=18 (I subtracted 34 from both sides)
x(89y-1)=18 (Since both terms on the left side included an x, I was able to factor out an x and put it out front.)
89y-1=18/x (Dividing everything by x is the next logical step in isolating y)
89y=18/x+1 (Further isolating y by adding 1 to each side)
y=18/89x+1/89 (Final step is dividing everything by 89)
Solving For x
89xy+34-x=52
89xy-x=18 (I subtracted 34 from both sides)
x(89y-1)=18 (Since both terms on the left side included an x, I was able to factor out an x and put it out front.)
x=18/(89y-1) (Dividing everything by the parentheses was the final step in isolating x. It cannot be further simplified.)

if you have to find y: X can not be zero so: 89xy+34-x=52 -> 52+x=89xy+34 -> 52+x-34=89xy -> (52-34+x)/x=89y -> 89y=52-34 -> 89y=18 -> y=18/89 MinedAndCrafted5

You made just a few errors. First, x could be 0, as this is just a function. You shouldn't have gotten a single number by simplifying a function, either. Also, you can't factor out an x from (52-34+x). x shouldn't cancel out at any point in simplifying this.

Alright math geniuses! I need to borrow your brains for a day. So I got a test on Friday, and one thing in it is Bedmas. I suck at it. (Even tho people say it's like the easiest thing ever.) Also note, it's in French, so it translates into Pedmas. And Ye, I suck. SO TELL ME EVERYTHING ABOUT IT.

Also, I can kind of help with really simple French if anyone wants.

Sorry for double post, too lazy to edit./ You're right, but I doubt you would need to factor it out. There's a much easier way, but it takes a while of explaining, and I don't feel like it.

Order of operations is pretty straightforward. The acronym PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. (As Pandq already mentioned) This is simply the order in which you solve things when faced with simplifying a problem. Figure out anything inside parentheses first, then solve anything that has an exponent on it next.

Multiplication and division come after exponents and parentheses. Multiplication and division are actually the same thing in reverse, (1/3 is the same as 1*0.3333...) so you can multiply and divide things in whatever order you want and it won't change the answer.

Addition and subtraction are also the same thing, just reverses of each other. (1+3 is the same as 1- negative 3) You can do addition and subtraction in whatever order you want and get the same answer.

Example:
Simplify this problem: x=(2(4+5)-8^2+6)/4
x=(2(9)-8^2+6)/4 (Solve the parentheses that you can first. The larger parentheses cannot be solved yet, as we need to do more algebra first.)
x=(2(9)-64+6)/4 (Solve the exponent, which is indicated by a ^ on a computer. 8 squared is 64. Note that it is not negative 8 squared, it is just 8 squared. The minus in front of the eight only makes it a negative if it has no exponents.)
x=(18-64+6)/4 (Do whatever multiplication or division you can.)
x=(-40)/4 (Now that you have finished simplifying the parentheses, you can divide by 4.)
x=-10

You mean Pemdas? Please Excuse My Dear Aunt Sally.

Pemdas, Pedmas, Pemdsa, Pedmsa are all the same thing. It doesn't matter which way around you put the division/multiplication and addition/subtraction.

Anyway, I sort of need help for examples like these:
(simplify)

3x^3y^-1z^-1/x^-4y^0x^0

(3x^2y^-2/12x^6y^3)^3
(like do you multiply the coefficients with the exponent and cube the exponents inside or wat)

My mathematics teacher doesn't give us actual notes and just examples, plus she doesn't explain anything so it's kind of hard to learn anything... I'm usually good in this subject but not when I have a crap teacher....

first one would be 3x^-1y^-1z^-1 (assuming im reading it right)
second would be (x^-4y^-5/12)^3 again assuming im reading it right
