Solve 100+10%+x=15

$$100+10 \% +x=15$$

Solve for x

$$x = -\frac{851}{10} = -85\frac{1}{10} = -85.1$$

Steps for Solving Linear Equation

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

$$100+\frac{1}{10}+x=15$$

Convert 100 to fraction \frac{1000}{10}.

$$\frac{1000}{10}+\frac{1}{10}+x=15$$

Since \frac{1000}{10} and \frac{1}{10} have the same denominator, add them by adding their numerators.

$$\frac{1000+1}{10}+x=15$$

Add 1000 and 1 to get 1001.

$$\frac{1001}{10}+x=15$$

Subtract \frac{1001}{10} from both sides.

$$x=15-\frac{1001}{10}$$

Convert 15 to fraction \frac{150}{10}.

$$x=\frac{150}{10}-\frac{1001}{10}$$

Since \frac{150}{10} and \frac{1001}{10} have the same denominator, subtract them by subtracting their numerators.

$$x=\frac{150-1001}{10}$$

Subtract 1001 from 150 to get -851.

$$x=-\frac{851}{10}$$
