Solve for t t-2/7=1/2

$t - \frac{2}{7} = \frac{1}{2}$

Add $\frac{2}{7}$ to both sides of the equation.

$t = \frac{1}{2} + \frac{2}{7}$

To write $\frac{1}{2}$ as a fraction with a common denominator, multiply by $\frac{7}{7}$ .

$t = \frac{1}{2} \cdot \frac{7}{7} + \frac{2}{7}$

To write $\frac{2}{7}$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$t = \frac{1}{2} \cdot \frac{7}{7} + \frac{2}{7} \cdot \frac{2}{2}$

Write each expression with a common denominator of $14$ , by multiplying each by an appropriate factor of $1$ .

Multiply $\frac{1}{2}$ by $\frac{7}{7}$ .

$t = \frac{7}{2 \cdot 7} + \frac{2}{7} \cdot \frac{2}{2}$

Multiply $2$ by $7$ .

$t = \frac{7}{14} + \frac{2}{7} \cdot \frac{2}{2}$

Multiply $\frac{2}{7}$ by $\frac{2}{2}$ .

$t = \frac{7}{14} + \frac{2 \cdot 2}{7 \cdot 2}$

Multiply $7$ by $2$ .

$t = \frac{7}{14} + \frac{2 \cdot 2}{14}$

Combine the numerators over the common denominator.

$t = \frac{7 + 2 \cdot 2}{14}$

Simplify the numerator.
