1-34.

For each of the equations below, solve for $y$ in terms of $x$ .

$2x-3y=12$
Step 1(a):
$\begin{array} 2x-3y=12\\ \quad -2x=-2x \qquad \quad \text{Subtract} \; 2x \; \text{from both sides}\\ \quad -3y=-2x+12 \end{array}$

Step 2(a):
$-3y=-2x+12$
Divide both sides by $-3$ .
Answer (a):
$y=\frac{2}{3}x-4$

$5x+2y=7$
Hint (b):
Use similar steps to solve for $y$ in terms of $x$ .
