Solve 2/7+x=3/4

$$\frac { 2 } { 7 } + x = \frac { 3 } { 4 }$$

Solve for x

$$x=\frac{13}{28}\approx 0.464285714$$

Steps for Solving Linear Equation

Subtract \frac{2}{7} from both sides.

$$x=\frac{3}{4}-\frac{2}{7}$$

Least common multiple of 4 and 7 is 28. Convert \frac{3}{4} and \frac{2}{7} to fractions with denominator 28.

$$x=\frac{21}{28}-\frac{8}{28}$$

Since \frac{21}{28} and \frac{8}{28} have the same denominator, subtract them by subtracting their numerators.

$$x=\frac{21-8}{28}$$

Subtract 8 from 21 to get 13.

$$x=\frac{13}{28}$$
