Solve 5x+50%=70

$$5 x + 50 \% = 70$$

Solve for x

$$x = \frac{139}{10} = 13\frac{9}{10} = 13.9$$

Steps for Solving Linear Equation

Reduce the fraction \frac{50}{100} to lowest terms by extracting and canceling out 50.

$$5x+\frac{1}{2}=70$$

Subtract \frac{1}{2} from both sides.

$$5x=70-\frac{1}{2}$$

Convert 70 to fraction \frac{140}{2}.

$$5x=\frac{140}{2}-\frac{1}{2}$$

Since \frac{140}{2} and \frac{1}{2} have the same denominator, subtract them by subtracting their numerators.

$$5x=\frac{140-1}{2}$$

Subtract 1 from 140 to get 139.

$$5x=\frac{139}{2}$$

Divide both sides by 5.

$$x=\frac{\frac{139}{2}}{5}$$

Express \frac{\frac{139}{2}}{5} as a single fraction.

$$x=\frac{139}{2\times 5}$$

Multiply 2 and 5 to get 10.

$$x=\frac{139}{10}$$
