3 x - y = 1

$3 x - y = 1$

Step 1

Add

y

$y$ to both sides of the equation.

3 x = 1 + y

$3 x = 1 + y$

Step 2

Divide each term in

3 x = 1 + y

$3 x = 1 + y$ by

3

$3$ and simplify.

Step 2.1

Divide each term in

3 x = 1 + y

$3 x = 1 + y$ by

3

$3$ .

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

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

Step 2.2.1.1

Cancel the common factor.

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

Step 2.2.1.2

Divide

$x$ by

$1$ .

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

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

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

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