Solve x+x*30%=40

$$x + x \cdot 30 \% = 40$$

Solve for x

$$x = \frac{400}{13} = 30\frac{10}{13} \approx 30.769230769$$

Steps for Solving Linear Equation

Reduce the fraction \frac{30}{100} to lowest terms by extracting and canceling out 10.

$$x+x\times \frac{3}{10}=40$$

Combine x and x\times \frac{3}{10} to get \frac{13}{10}x.

$$\frac{13}{10}x=40$$

Multiply both sides by \frac{10}{13}, the reciprocal of \frac{13}{10}.

$$x=40\times \frac{10}{13}$$

Express 40\times \frac{10}{13} as a single fraction.

$$x=\frac{40\times 10}{13}$$

Multiply 40 and 10 to get 400.

$$x=\frac{400}{13}$$
