Solve 0.8*4-x=3.2div8

$$0.8 \times 4-x=3.2 \div 8$$

Solve for x

$$x=2.8$$

Steps for Solving Linear Equation

Multiply 0.8 and 4 to get 3.2.

$$3.2-x=\frac{3.2}{8}$$

Expand \frac{3.2}{8} by multiplying both numerator and the denominator by 10.

$$3.2-x=\frac{32}{80}$$

Reduce the fraction \frac{32}{80} to lowest terms by extracting and canceling out 16.

$$3.2-x=\frac{2}{5}$$

Subtract 3.2 from both sides.

$$-x=\frac{2}{5}-3.2$$

Convert decimal number 3.2 to fraction \frac{32}{10}. Reduce the fraction \frac{32}{10} to lowest terms by extracting and canceling out 2.

$$-x=\frac{2}{5}-\frac{16}{5}$$

Since \frac{2}{5} and \frac{16}{5} have the same denominator, subtract them by subtracting their numerators.

$$-x=\frac{2-16}{5}$$

Subtract 16 from 2 to get -14.

$$-x=-\frac{14}{5}$$

Multiply both sides by -1.

$$x=\frac{14}{5}$$
