A-23.

Solve each equation for the indicated variable.

1. $t=an+b\ (\text{for }b)$

• Subtract '$an$' from both sides.

1. $\frac{y}{3}-a=b\ (\text{for }y)$

• Add '$a$' to both sides.

• Multiply both sides by $3$.

1. $m=\frac{y}{x}\ (\text{for }y)$

• See Step 2 of part (b).

1. $m=\frac{y}{x}\ (\text{for }x)$

• Look at the answer you got for part (c).
