1/3(x+4)=20

1/3x+4/3=20

1/3x=56/3

x= (56/3) / (1/3)

x= 56
[tex] \frac{1}{3} (x+4) = 20 \\ \\ simplify \\ \\ \frac{1}{3} x + \frac{4}{3} = 20 \\ \\ Subtract >>by >> \frac{4}{3} \\ \\ \frac{1}{3} x + \frac{4}{3} - \frac{4}{3} = 20 - \frac{4}{3 \\ \\} \\ \\ Divide > by > \frac{1}{3} \\ \\ and > your>answer>is = x = 56[/tex]
