Step 1.1

Combine $x$ and $\frac{4}{9}$ .

$y = - \frac{x \cdot 4}{9} - 3$

$y = - \frac{7}{5} x - 3$

Step 1.2

Move $4$ to the left of $x$ .

$y = - \frac{4 x}{9} - 3$

$y = - \frac{7}{5} x - 3$

$y = - \frac{4 x}{9} - 3$

$y = - \frac{7}{5} x - 3$

Step 2

Simplify each term.

Step 2.1

Combine $x$ and $\frac{7}{5}$ .

$y = - \frac{x \cdot 7}{5} - 3$

$y = - \frac{4 x}{9} - 3$

Step 2.2

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

$y = - \frac{7 x}{5} - 3$

$y = - \frac{4 x}{9} - 3$

$y = - \frac{7 x}{5} - 3$

$y = - \frac{4 x}{9} - 3$

Step 3

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

$(0, - 3)$
