Solve (28+x)*2=10.4

$$( 28 + x ) \times 2 = 10.4$$

Solve for x

$$x=-22.8$$

Steps for Solving Linear Equation

Divide both sides by 2.

$$28+x=\frac{10.4}{2}$$

Expand \frac{10.4}{2} by multiplying both numerator and the denominator by 10.

$$28+x=\frac{104}{20}$$

Reduce the fraction \frac{104}{20} to lowest terms by extracting and canceling out 4.

$$28+x=\frac{26}{5}$$

Subtract 28 from both sides.

$$x=\frac{26}{5}-28$$

Convert 28 to fraction \frac{140}{5}.

$$x=\frac{26}{5}-\frac{140}{5}$$

Since \frac{26}{5} and \frac{140}{5} have the same denominator, subtract them by subtracting their numerators.

$$x=\frac{26-140}{5}$$

Subtract 140 from 26 to get -114.

$$x=-\frac{114}{5}$$
