Steps for Solving Linear Equation

Reduce the fraction \frac{45}{100} to lowest terms by extracting and canceling out 5.

$$\frac{9}{20}x-\frac{15}{100}x=18$$

Reduce the fraction \frac{15}{100} to lowest terms by extracting and canceling out 5.

$$\frac{9}{20}x-\frac{3}{20}x=18$$

Combine \frac{9}{20}x and -\frac{3}{20}x to get \frac{3}{10}x.

$$\frac{3}{10}x=18$$

Multiply both sides by \frac{10}{3}, the reciprocal of \frac{3}{10}.

$$x=18\times \frac{10}{3}$$

Express 18\times \frac{10}{3} as a single fraction.

$$x=\frac{18\times 10}{3}$$

Multiply 18 and 10 to get 180.

$$x=\frac{180}{3}$$

Divide 180 by 3 to get 60.

$$x=60$$
