y*y = 11y Divide both sides by y: y = 11
y=-2
y-1/y2-y+1=y/y-1
Start with any number - say x. Pick any other number which is not 0, say y. Then, if you multiply x by y and then divide the result by y you will be back to x. Thus, "multiply by y" followed by "divide by y" is equivalent to do nothing. The first undoes the second. Also, it works in reverse in the sense that you can divide by y first and multiply by y afterwards.
The answer will depend on what you wish to divide it by. If you wish to divide it by a variable, y, then the relevant expression is x/y.

Slip-per-y.
y=-2
y-1/y2-y+1=y/y-1

x as a percentage of y = x/y * 100% divide x by y then multiply by 100%
Flip the second fraction upside down and multiply. For example, if you want to divide (a/b) by (x/y), multiply (a/b) by (y/x).
(y^2 - 4) / (y + 2) = [(y -2)(y+2)]/(y+2) = y-2
You divide the word army into syllables like this- arm----y
A y chart is drawn on a paper dividing the paper into three by drawing a y to divide it. It is used by brainstorming.
