Algebra: A Combined Approach (4th Edition)

z = $\frac{9}{5}$
$\frac{2(z + 3)}{3}$ = 5 - z Distribute: $\frac{2z + 6}{3}$ = 5 - z Multiply both sides by 3: 2z + 6 = 3(5 - z) Distribute: 2z + 6 = 15 - 3z Add 3z to both sides: 5z + 6 = 15 Subtract 6 from both sides: 5z = 9 Divide both sides by 5: z = $\frac{9}{5}$
