# How do you solve the system of equations 9x + 3y = - 18 and 3x - 5y = - 24?

x=-3
y=3

#### Explanation:

= $9 x + 3 y = - 18$
Divide 3 on both sides

= $3 x + y = - 6$

Now Subtracting

=$\left(3 x + y = - 6\right) - \left(3 x - 5 y = - 24\right)$

= $6 y = 18$

= $y = 3$

For $x$ doing putting in following

=$3 x - 5 y = - 24$

= $3 x - 5 \left(3\right) = - 24$

= $3 x = - 9$

= $x = - 3$
