7 x - y = 14

$7 x - y = 14$

Step 1

Add

y

$y$ to both sides of the equation.

7 x = 14 + y

$7 x = 14 + y$

Step 2

Divide each term in

7 x = 14 + y

$7 x = 14 + y$ by

7

$7$ and simplify.

Step 2.1

Divide each term in

7 x = 14 + y

$7 x = 14 + y$ by

7

$7$ .

\frac{7 x}{7} = \frac{14}{7} + \frac{y}{7}

$\frac{7 x}{7} = \frac{14}{7} + \frac{y}{7}$

Step 2.2.1.1

Cancel the common factor.

$\frac{7 x}{7} = \frac{14}{7} + \frac{y}{7}$

Step 2.2.1.2

Divide

$x$ by

$1$ .

$x = \frac{14}{7} + \frac{y}{7}$

$x = \frac{14}{7} + \frac{y}{7}$

$x = \frac{14}{7} + \frac{y}{7}$

Step 2.3

Simplify the right side.

Step 2.3.1

Divide

$14$ by

$7$ .

$x = 2 + \frac{y}{7}$

$x = 2 + \frac{y}{7}$

$x = 2 + \frac{y}{7}$

$7 x - y = 14$
