$x = \frac{4 a + b}{3}$

Step 1

Rewrite the equation as $\frac{4 a + b}{3} = x$ .

$\frac{4 a + b}{3} = x$

Step 2

Multiply both sides by $3$ .

$\frac{4 a + b}{3} \cdot 3 = x \cdot 3$

Cancel the common factor.

$\frac{4 a + b}{3} \cdot 3 = x \cdot 3$

Step 3.1.1.2

Rewrite the expression.

$4 a + b = x \cdot 3$

$4 a + b = x \cdot 3$

$4 a + b = x \cdot 3$

Step 3.2

Simplify the right side.

Step 3.2.1

Move $3$ to the left of $x$ .

$4 a + b = 3 x$

$4 a + b = 3 x$

$4 a + b = 3 x$

Step 4

Subtract $4 a$ from both sides of the equation.

$b = 3 x - 4 a$
