$153 = \frac{3}{2} x + 3$

Step 1

Rewrite the equation as $\frac{3}{2} x + 3 = 153$ .

$\frac{3}{2} x + 3 = 153$

Step 2

Combine $\frac{3}{2}$ and $x$ .

$\frac{3 x}{2} + 3 = 153$

Step 3

Move all terms not containing $x$ to the right side of the equation.

Step 3.1

Subtract $3$ from both sides of the equation.

$\frac{3 x}{2} = 153 - 3$

Step 3.2

Subtract $3$ from $153$ .

$\frac{3 x}{2} = 150$

Step 4

Multiply both sides of the equation by $\frac{2}{3}$ .

$\frac{2}{3} \cdot \frac{3 x}{2} = \frac{2}{3} \cdot 150$
