Solve for x 2x-y=4

$2 x - y = 4$

Step 1

Add $y$ to both sides of the equation.

$2 x = 4 + y$

Step 2

Divide each term in $2 x = 4 + y$ by $2$ and simplify.

Divide each term in $2 x = 4 + y$ by $2$ .

$\frac{2 x}{2} = \frac{4}{2} + \frac{y}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 x}{2} = \frac{4}{2} + \frac{y}{2}$

Divide $x$ by $1$ .

$x = \frac{4}{2} + \frac{y}{2}$

Simplify the right side.

Divide $4$ by $2$ .

$x = 2 + \frac{y}{2}$
