Solve x-1/1+2=3

$$\frac { x - 1 } { 1 + 2 } = 3$$

Solve for x

$$x=10$$

Steps for Solving Linear Equation

Add 1 and 2 to get 3.

$$\frac{x-1}{3}=3$$

Divide each term of x-1 by 3 to get \frac{1}{3}x-\frac{1}{3}.

$$\frac{1}{3}x-\frac{1}{3}=3$$

Add \frac{1}{3} to both sides.

$$\frac{1}{3}x=3+\frac{1}{3}$$

Convert 3 to fraction \frac{9}{3}.

$$\frac{1}{3}x=\frac{9}{3}+\frac{1}{3}$$

Since \frac{9}{3} and \frac{1}{3} have the same denominator, add them by adding their numerators.

$$\frac{1}{3}x=\frac{9+1}{3}$$

Add 9 and 1 to get 10.

$$\frac{1}{3}x=\frac{10}{3}$$

Multiply both sides by 3, the reciprocal of \frac{1}{3}.

$$x=\frac{10}{3}\times 3$$

Cancel out 3 and 3.

$$x=10$$
