Pre-Algebra Examples

$2 x = 12 + 2 y$

Step 1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 2

Rewrite in slope-intercept form.

Step 2.1

Rewrite the equation as $12 + 2 y = 2 x$ .

$12 + 2 y = 2 x$

Step 2.2

Subtract $12$ from both sides of the equation.

$2 y = 2 x - 12$

Step 2.3

Divide each term in $2 y = 2 x - 12$ by $2$ and simplify.
