Step 1.1.1.1

Move the leading negative in $- \frac{1}{3}$ into the numerator.

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

Step 1.1.1.2

Factor $3$ out of $- 3$ .

$x = \frac{- 1}{3} \cdot (3 (- 1)) + 3$

Step 1.1.1.3

Cancel the common factor.

$x = \frac{- 1}{3} \cdot (3 \cdot - 1) + 3$

Step 1.1.1.4

Rewrite the expression.

$x = - 1 \cdot - 1 + 3$

Step 1.1.2

Multiply $- 1$ by $- 1$ .

$x = 1 + 3$

Step 1.2

Add $1$ and $3$ .

$x = 4$

Step 2

Graph each side of the equation. The solution is the x-value of the point of intersection.

$x = 4$
