Solve for x y=2x+3

$y = 2 x + 3$

Step 1

Rewrite the equation as $2 x + 3 = y$ .

$2 x + 3 = y$

Step 2

Subtract $3$ from both sides of the equation.

$2 x = y - 3$

Step 3

Divide each term in $2 x = y - 3$ by $2$ and simplify.

Divide each term in $2 x = y - 3$ by $2$ .

$\frac{2 x}{2} = \frac{y}{2} + \frac{- 3}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 x}{2} = \frac{y}{2} + \frac{- 3}{2}$

Divide $x$ by $1$ .

$x = \frac{y}{2} + \frac{- 3}{2}$

Simplify the right side.

Move the negative in front of the fraction.

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