Solve 1=(0,1+x)20

$$1 = ( 0,1 + x ) 20$$

Solve for x

$$x=-0,05$$

Steps for Solving Linear Equation

Divide both sides by 20.

$$\frac{1}{20}=0,1+x$$

Swap sides so that all variable terms are on the left hand side.

$$0,1+x=\frac{1}{20}$$

Subtract 0,1 from both sides.

$$x=\frac{1}{20}-0,1$$

Convert decimal number 0,1 to fraction \frac{1}{10}.

$$x=\frac{1}{20}-\frac{1}{10}$$

Least common multiple of 20 and 10 is 20. Convert \frac{1}{20} and \frac{1}{10} to fractions with denominator 20.

$$x=\frac{1}{20}-\frac{2}{20}$$

Since \frac{1}{20} and \frac{2}{20} have the same denominator, subtract them by subtracting their numerators.

$$x=\frac{1-2}{20}$$

Subtract 2 from 1 to get -1.

$$x=-\frac{1}{20}$$
