$y = \frac{1}{7} x + 3$

Step 1

Rewrite the equation as $\frac{1}{7} x + 3 = y$ .

$\frac{1}{7} x + 3 = y$

Step 2

Combine $\frac{1}{7}$ and $x$ .

$\frac{x}{7} + 3 = y$

Step 3

Subtract $3$ from both sides of the equation.

$\frac{x}{7} = y - 3$

Step 4

Multiply both sides of the equation by $7$ .

$7 \frac{x}{7} = 7 (y - 3)$

Step 5

Simplify both sides of the equation.

Step 5.1.1.1

Cancel the common factor.

$7 \frac{x}{7} = 7 (y - 3)$

Step 5.1.1.2

Rewrite the expression.

$x = 7 (y - 3)$

$x = 7 (y - 3)$

$x = 7 (y - 3)$

Step 5.2.1.1

Apply the distributive property.

$x = 7 y + 7 \cdot - 3$

Step 5.2.1.2

Multiply $7$ by $- 3$ .

$x = 7 y - 21$

$x = 7 y - 21$

$x = 7 y - 21$

$x = 7 y - 21$
