Solve the equation. Justify each step
Wewaii [24]

Given

9(h-4) = 5(3h-2)

Distribute 9 on the left hand side and 5 on the right hand side (distributive property of addition)

9h-36=15h-10

Add 36 to both sides (addition property of equality)

9h=15h+26

Subtract 15h to both sides (subtraction property of equality)

-6h=26

Divide both sides by -6 (division property of equality)

h=-\dfrac{26}{6}=-\dfrac{13}{3}
