Question

2. If y(x-1)=z then x=

Answer 1

Start by dividing both sides by y

Answer 2

here is the first step. Like Caleb said, divide both sides by y
\[ \frac{y(x-1)}{y} = \frac{z}{y} \]
the left side can be simplified, Can you see how?

Answer 3

yes...thanks so much.

Answer 4

what did you get?

Answer 5

i got x=z/y+1

Answer 6

you could also write the answer as
\[ \frac{z}{y}+\frac{y}{y} \] or
\[ \frac{z+y}{y} \]
just in case you see that in a multiple choice answer.

Answer 7

thanks very much!!! :)
