Solve -21/3x=7/15

$$- 2 \frac { 1 } { 3 } x = \frac { 7 } { 15 }$$

Solve for x

$$x=-\frac{1}{5}=-0.2$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 15, the least common multiple of 3,15.

$$15\left(-\frac{2\times 3+1}{3}\right)x=7$$

Multiply 2 and 3 to get 6.

$$15\left(-\frac{6+1}{3}\right)x=7$$

Add 6 and 1 to get 7.

$$15\left(-\frac{7}{3}\right)x=7$$

Express 15\left(-\frac{7}{3}\right) as a single fraction.

$$\frac{15\left(-7\right)}{3}x=7$$

Multiply 15 and -7 to get -105.

$$\frac{-105}{3}x=7$$

Divide -105 by 3 to get -35.

$$-35x=7$$

Divide both sides by -35.

$$x=\frac{7}{-35}$$

Reduce the fraction \frac{7}{-35} to lowest terms by extracting and canceling out 7.

$$x=-\frac{1}{5}$$
