Solve each equation for the indicated variable.

1.  $y = m x + b\quad (\text{for } b )$

Isolate $b$ on one side by moving $mx$ to the other.

1.  $y = m x + b \quad ( \text { for } x )$

Isolate $x$ on one side by moving $b$ and then dividing by $m$.

1.  $I = p r t \quad ( \text { for } t )$

Refer to parts (a) and (b) for help.

1.  $A = p + p r t \quad ( \text { for } t )$

Refer to parts (a) and (b) for help.

$\frac{A-p}{pr}$
