Basic Math Examples

$\frac{2}{5} + \frac{1}{4} t = \frac{1}{5}$

Step 1

Combine $\frac{1}{4}$ and $t$ .

$\frac{2}{5} + \frac{t}{4} = \frac{1}{5}$

Step 2

Move all terms not containing $t$ to the right side of the equation.

Step 2.1

Subtract $\frac{2}{5}$ from both sides of the equation.

$\frac{t}{4} = \frac{1}{5} - \frac{2}{5}$

Step 2.2

Combine the numerators over the common denominator.

$\frac{t}{4} = \frac{1 - 2}{5}$

Step 2.3

Subtract $2$ from $1$ .

$\frac{t}{4} = \frac{- 1}{5}$

Step 2.4

Move the negative in front of the fraction.

$\frac{t}{4} = - \frac{1}{5}$

Step 3

Multiply both sides of the equation by $4$ .

$4 \frac{t}{4} = 4 (- \frac{1}{5})$

Step 4

Simplify both sides of the equation.
