Solve 7/10-x=2/7

$$\frac { 7 } { 10 } - x = \frac { 2 } { 7 }$$

Solve for x

$$x=\frac{29}{70}\approx 0.414285714$$

Steps for Solving Linear Equation

Subtract \frac{7}{10} from both sides.

$$-x=\frac{2}{7}-\frac{7}{10}$$

Least common multiple of 7 and 10 is 70. Convert \frac{2}{7} and \frac{7}{10} to fractions with denominator 70.

$$-x=\frac{20}{70}-\frac{49}{70}$$

Since \frac{20}{70} and \frac{49}{70} have the same denominator, subtract them by subtracting their numerators.

$$-x=\frac{20-49}{70}$$

Subtract 49 from 20 to get -29.

$$-x=-\frac{29}{70}$$

Multiply both sides by -1.

$$x=\frac{29}{70}$$
