Solve 20left(3/20+w+3/20+wright)=18

$$20 \left( \frac{ 3 }{ 20 } +w+ \frac{ 3 }{ 20 } +w \right) =18$$

Solve for w

$$w=\frac{3}{10}=0.3$$

Steps for Solving Linear Equation

Divide both sides by 20.

$$\frac{3}{20}+w+\frac{3}{20}+w=\frac{18}{20}$$

Reduce the fraction \frac{18}{20} to lowest terms by extracting and canceling out 2.

$$\frac{3}{20}+w+\frac{3}{20}+w=\frac{9}{10}$$

Since \frac{3}{20} and \frac{3}{20} have the same denominator, add them by adding their numerators.

$$\frac{3+3}{20}+w+w=\frac{9}{10}$$

Add 3 and 3 to get 6.

$$\frac{6}{20}+w+w=\frac{9}{10}$$

Reduce the fraction \frac{6}{20} to lowest terms by extracting and canceling out 2.

$$\frac{3}{10}+w+w=\frac{9}{10}$$

Combine w and w to get 2w.

$$\frac{3}{10}+2w=\frac{9}{10}$$

Subtract \frac{3}{10} from both sides.

$$2w=\frac{9}{10}-\frac{3}{10}$$

Since \frac{9}{10} and \frac{3}{10} have the same denominator, subtract them by subtracting their numerators.

$$2w=\frac{9-3}{10}$$

Subtract 3 from 9 to get 6.

$$2w=\frac{6}{10}$$

Reduce the fraction \frac{6}{10} to lowest terms by extracting and canceling out 2.

$$2w=\frac{3}{5}$$

Divide both sides by 2.

$$w=\frac{\frac{3}{5}}{2}$$

Express \frac{\frac{3}{5}}{2} as a single fraction.

$$w=\frac{3}{5\times 2}$$

Multiply 5 and 2 to get 10.

$$w=\frac{3}{10}$$
