Pre-Algebra Examples

$x = \frac{1}{2} y + 2$

Step 1

Rewrite the equation as $\frac{1}{2} y + 2 = x$ .

$\frac{1}{2} y + 2 = x$

Step 2

Combine $\frac{1}{2}$ and $y$ .

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

Step 3

Subtract $2$ from both sides of the equation.

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

Step 4

Multiply both sides of the equation by $2$ .

$2 \frac{y}{2} = 2 (x - 2)$

Step 5

Simplify both sides of the equation.

Step 5.1.1.1

Cancel the common factor.

$2 \frac{y}{2} = 2 (x - 2)$

Step 5.1.1.2

Rewrite the expression.

$y = 2 (x - 2)$

$y = 2 (x - 2)$

$y = 2 (x - 2)$

Step 5.2.1.1

Apply the distributive property.

$y = 2 x + 2 \cdot - 2$

Step 5.2.1.2

Multiply $2$ by $- 2$ .

$y = 2 x - 4$

$y = 2 x - 4$

$y = 2 x - 4$

$y = 2 x - 4$
