Pre-Algebra Examples

$x - \frac{1}{8} = \frac{3}{8}$

Step 1

Add $\frac{1}{8}$ to both sides of the equation.

$x = \frac{3}{8} + \frac{1}{8}$

Step 2

Combine the numerators over the common denominator.

$x = \frac{3 + 1}{8}$

Step 3

Add $3$ and $1$ .

$x = \frac{4}{8}$

Step 4

Cancel the common factor of $4$ and $8$ .

Step 4.2.1

Factor $4$ out of $8$ .

$x = \frac{4 \cdot 1}{4 \cdot 2}$

Step 4.2.2

Cancel the common factor.

$x = \frac{4 \cdot 1}{4 \cdot 2}$

Step 4.2.3

Rewrite the expression.

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

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

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

Step 5

The result can be shown in multiple forms.

Exact Form:

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

Decimal Form:

$x = 0.5$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
