Solve y+2/5leq7/10

$$y + \frac { 2 } { 5 } \leq \frac { 7 } { 10 }$$

Solve for y

$$y\leq \frac{3}{10}$$

Solution Steps

Subtract \frac{2}{5} from both sides.

$$y\leq \frac{7}{10}-\frac{2}{5}$$

Least common multiple of 10 and 5 is 10. Convert \frac{7}{10} and \frac{2}{5} to fractions with denominator 10.

$$y\leq \frac{7}{10}-\frac{4}{10}$$

Since \frac{7}{10} and \frac{4}{10} have the same denominator, subtract them by subtracting their numerators.

$$y\leq \frac{7-4}{10}$$

Subtract 4 from 7 to get 3.

$$y\leq \frac{3}{10}$$
