Solve x+3/10=-2/5

$$x + \frac { 3 } { 10 } = - \frac { 2 } { 5 }$$

Solve for x

$$x=-\frac{7}{10}=-0.7$$

Steps for Solving Linear Equation

Subtract \frac{3}{10} from both sides.

$$x=-\frac{2}{5}-\frac{3}{10}$$

Least common multiple of 5 and 10 is 10. Convert -\frac{2}{5} and \frac{3}{10} to fractions with denominator 10.

$$x=-\frac{4}{10}-\frac{3}{10}$$

Since -\frac{4}{10} and \frac{3}{10} have the same denominator, subtract them by subtracting their numerators.

$$x=\frac{-4-3}{10}$$

Subtract 3 from -4 to get -7.

$$x=-\frac{7}{10}$$
