anonymous one year ago Solve for y. x+a=yb I don't understand what I'm supposed to do?

1. butterflydreamer

If you want to solve for "y", it means you want to make "y" the subject :) So we want to end up with something like y = .......... Since we have: yb = x + a What should we divide both sides by to get "y = ...." ?

2. anonymous

The answers are A) y=x+a-b B) y=-(x+a)/b C) y=(x+a)/b

Divide which sides by y?

4. butterflydreamer

$yb = x + a$ Therefore we know that "yb" means "y TIMES b" right? :) So if we want a "y" by itself, we need to divide BOTH sides by "b" and we'll end up with something that looks like this: $\frac{ yb }{ b } = \frac{ x + a }{ b }$ On the left side of the equal sign the b's will cancel out and leave us with: $y = \frac{ x+a }{ b }$

Oh! I get it now. Thank you
