Step 1

Simplify each term.

Tap for more steps...

Step 1.1

Combine $x$ and $\frac{7}{3}$ .

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

$y = x + 7$

Step 1.2

Move $7$ to the left of $x$ .

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

$y = x + 7$

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

$y = x + 7$

Step 2

Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution.
