Solve 12-xdiv2.5=1.8

$$12-x \div 2.5=1.8$$

Solve for x

$$x=25.5$$

Steps for Solving Linear Equation

Subtract 12 from both sides.

$$-\frac{x}{2.5}=1.8-12$$

Subtract 12 from 1.8 to get -10.2.

$$-\frac{x}{2.5}=-10.2$$

Divide both sides by -1.

$$\frac{x}{2.5}=\frac{-10.2}{-1}$$

Expand \frac{-10.2}{-1} by multiplying both numerator and the denominator by 10.

$$\frac{x}{2.5}=\frac{-102}{-10}$$

Reduce the fraction \frac{-102}{-10} to lowest terms by extracting and canceling out -2.

$$\frac{x}{2.5}=\frac{51}{5}$$

Multiply both sides by 2.5.

$$x=\frac{51}{5}\times 2.5$$

Convert decimal number 2.5 to fraction \frac{25}{10}. Reduce the fraction \frac{25}{10} to lowest terms by extracting and canceling out 5.

$$x=\frac{51}{5}\times \frac{5}{2}$$

Multiply \frac{51}{5} times \frac{5}{2} by multiplying numerator times numerator and denominator times denominator.

$$x=\frac{51\times 5}{5\times 2}$$

Cancel out 5 in both numerator and denominator.

$$x=\frac{51}{2}$$
