Solve x+21%x=100

$$x+21 \% x=100$$

Solve for x

$$x = \frac{10000}{121} = 82\frac{78}{121} \approx 82.644628099$$

Steps for Solving Linear Equation

Combine x and \frac{21}{100}x to get \frac{121}{100}x.

$$\frac{121}{100}x=100$$

Multiply both sides by \frac{100}{121}, the reciprocal of \frac{121}{100}.

$$x=100\times \frac{100}{121}$$

Express 100\times \frac{100}{121} as a single fraction.

$$x=\frac{100\times 100}{121}$$

Multiply 100 and 100 to get 10000.

$$x=\frac{10000}{121}$$
