Answer:
y = [tex]\frac{3x-72}{9}[/tex] = [tex]\frac{1}{3}[/tex] x - 8
Step-by-step explanation:
given
3x - 9y = 72 ( subtract 3x from both sides )
- 9y = 72 - 3x ( multiply both sides by - 1 )
9y = 3x - 72 ( divide both sides by 9 )
y = [tex]\frac{3x-72}{9}[/tex]
y = [tex]\frac{3}{9}[/tex] x - [tex]\frac{72}{9}[/tex] = [tex]\frac{1}{3}[/tex] x - 8
