A:
Answer:4y = (3x - 9) Step-by-step explanation:4y = 3x - 9[tex]\frac{4y}{4}= \frac{3}{4} -\frac{9}{4}[/tex][tex]y=\frac{3}{4} -2.25[/tex]Now we know y.Solve for x.4y = 3x - 9              + 9+94y + 9 = 3x[tex]\frac{4y}{3} +\frac{9}{3} = \frac{3x}{3}[/tex][tex]x = \frac{4y}{3} +3[/tex][tex]y=\frac{3(\frac{4y}{3} +3)}{4}[/tex]
