Answer
a) $x=18$
b) $x=10$
Work Step by Step
a) $\frac{1}{3}x=6$
Multiply both sides by 3.
$x=6\times3$
Solve right side.
$x=18$
b) $\frac{1}{2}x-\frac{3}{2}=\frac{7}{2}$
Multiply both sides by 2.
2($\frac{1}{2}x-\frac{3}{2})=2(\frac{7}{2}$)
$x-3=7$
Move 3 to the right side.
$x= 7+3$
Solve right side.
$x=10$
