Solve 2x+40%=7.2

$$2 x + 40 \% = 7.2$$

Solve for x

$$x=3.4$$

Steps for Solving Linear Equation

Reduce the fraction \frac{40}{100} to lowest terms by extracting and canceling out 20.

$$2x+\frac{2}{5}=7.2$$

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

$$2x=7.2-\frac{2}{5}$$

Convert decimal number 7.2 to fraction \frac{72}{10}. Reduce the fraction \frac{72}{10} to lowest terms by extracting and canceling out 2.

$$2x=\frac{36}{5}-\frac{2}{5}$$

Since \frac{36}{5} and \frac{2}{5} have the same denominator, subtract them by subtracting their numerators.

$$2x=\frac{36-2}{5}$$

Subtract 2 from 36 to get 34.

$$2x=\frac{34}{5}$$

Divide both sides by 2.

$$x=\frac{\frac{34}{5}}{2}$$

Express \frac{\frac{34}{5}}{2} as a single fraction.

$$x=\frac{34}{5\times 2}$$

Multiply 5 and 2 to get 10.

$$x=\frac{34}{10}$$

Reduce the fraction \frac{34}{10} to lowest terms by extracting and canceling out 2.

$$x=\frac{17}{5}$$
