Solve for x 2(x+b)=a

$2 (x + b) = a$

Divide each term in $2 (x + b) = a$ by $2$ and simplify.

Divide each term in $2 (x + b) = a$ by $2$ .

$\frac{2 (x + b)}{2} = \frac{a}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 (x + b)}{2} = \frac{a}{2}$

Divide $x + b$ by $1$ .

$x + b = \frac{a}{2}$

Subtract $b$ from both sides of the equation.

$x = \frac{a}{2} - b$
