m - x = n - p , for x

• x = m - n + p

• x = n - p - m

• = -m - n - p

• x = m - n - p

what is the next step to finish solving for y in the equation

3y = -5x + 10

• subtract 3 from both sides

• subtract 3y from both sides

• divide all terms on both sides by 3

• divide all terms on both sides by 3y

• get rid of the negatives, stay positive

Solve for a:

 $a-c=d-r$  

•  $a=\frac{d-r}{c}$  

•  $a=d-r+c$  

•  $a=\frac{c}{d-r}$  

•  $a=cdr$
