$$x-70 \% x=30$$

Solve for x

$$x=100$$

Steps for Solving Linear Equation

Reduce the fraction \frac{70}{100} to lowest terms by extracting and canceling out 10.

$$x-\frac{7}{10}x=30$$

Combine x and -\frac{7}{10}x to get \frac{3}{10}x.

$$\frac{3}{10}x=30$$

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

$$x=30\times \frac{10}{3}$$

Express 30\times \frac{10}{3} as a single fraction.

$$x=\frac{30\times 10}{3}$$

Multiply 30 and 10 to get 300.

$$x=\frac{300}{3}$$

Divide 300 by 3 to get 100.

$$x=100$$
