Steps for Solving Linear Equation

Multiply both sides by 1.

$$4200\times 1=4000\times 5\times x$$

Multiply 4200 and 1 to get 4200.

$$4200=4000\times 5\times x$$

Swap sides so that all variable terms are on the left hand side.

$$4000\times 5\times x=4200$$

The equation is in standard form.

$$20000x=4200$$

Divide both sides by 20000.

$$\frac{20000x}{20000}=\frac{4200}{20000}$$

Dividing by 20000 undoes the multiplication by 20000.

$$x=\frac{4200}{20000}$$

Reduce the fraction \frac{4200}{20000} to lowest terms by extracting and canceling out 200.

$$x=\frac{21}{100}$$
