Solve 1/7+x=3/4

$$\frac { 1 } { 7 } + x = \frac { 3 } { 4 }$$

Solve for x

$$x=\frac{17}{28}\approx 0.607142857$$

Steps for Solving Linear Equation

Subtract \frac{1}{7} from both sides.

$$x=\frac{3}{4}-\frac{1}{7}$$

Least common multiple of 4 and 7 is 28. Convert \frac{3}{4} and \frac{1}{7} to fractions with denominator 28.

$$x=\frac{21}{28}-\frac{4}{28}$$

Since \frac{21}{28} and \frac{4}{28} have the same denominator, subtract them by subtracting their numerators.

$$x=\frac{21-4}{28}$$

Subtract 4 from 21 to get 17.

$$x=\frac{17}{28}$$
