Solve for x 2x+A=B

$2 x + A = B$

Step 1

Subtract $A$ from both sides of the equation.

$2 x = B - A$

Step 2

Divide each term in $2 x = B - A$ by $2$ and simplify.

Divide each term in $2 x = B - A$ by $2$ .

$\frac{2 x}{2} = \frac{B}{2} + \frac{- A}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 x}{2} = \frac{B}{2} + \frac{- A}{2}$

Divide $x$ by $1$ .

$x = \frac{B}{2} + \frac{- A}{2}$

Simplify the right side.

Move the negative in front of the fraction.

$x = \frac{B}{2} - \frac{A}{2}$
