Solve 2142=42(x-1)*42

$$2142=42(x-1) \times 42$$

Solve for x

$$x = \frac{31}{14} = 2\frac{3}{14} \approx 2.214285714$$

Steps for Solving Linear Equation

Multiply 42 and 42 to get 1764.

$$2142=1764\left(x-1\right)$$

Use the distributive property to multiply 1764 by x-1.

$$2142=1764x-1764$$

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

$$1764x-1764=2142$$

Add 1764 to both sides.

$$1764x=2142+1764$$

Add 2142 and 1764 to get 3906.

$$1764x=3906$$

Divide both sides by 1764.

$$x=\frac{3906}{1764}$$

Reduce the fraction \frac{3906}{1764} to lowest terms by extracting and canceling out 126.

$$x=\frac{31}{14}$$
