Solve (1+x)4=1.2

$$(1+x)4=1.2$$

Solve for x

$$x=-0.7$$

Steps for Solving Linear Equation

Divide both sides by 4.

$$1+x=\frac{1.2}{4}$$

Expand \frac{1.2}{4} by multiplying both numerator and the denominator by 10.

$$1+x=\frac{12}{40}$$

Reduce the fraction \frac{12}{40} to lowest terms by extracting and canceling out 4.

$$1+x=\frac{3}{10}$$

Subtract 1 from both sides.

$$x=\frac{3}{10}-1$$

Convert 1 to fraction \frac{10}{10}.

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

Since \frac{3}{10} and \frac{10}{10} have the same denominator, subtract them by subtracting their numerators.

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

Subtract 10 from 3 to get -7.

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