Solve 3(x-12)=2.1

$$3 ( x - 12 ) = 2.1$$

Solve for x

$$x=12.7$$

Steps for Solving Linear Equation

Divide both sides by 3.

$$x-12=\frac{2.1}{3}$$

Expand \frac{2.1}{3} by multiplying both numerator and the denominator by 10.

$$x-12=\frac{21}{30}$$

Reduce the fraction \frac{21}{30} to lowest terms by extracting and canceling out 3.

$$x-12=\frac{7}{10}$$

Add 12 to both sides.

$$x=\frac{7}{10}+12$$

Convert 12 to fraction \frac{120}{10}.

$$x=\frac{7}{10}+\frac{120}{10}$$

Since \frac{7}{10} and \frac{120}{10} have the same denominator, add them by adding their numerators.

$$x=\frac{7+120}{10}$$

Add 7 and 120 to get 127.

$$x=\frac{127}{10}$$
