Answer:
Step-by-step explanation: To solve this system, we can begin by solving for x in the second problem. This would look like:
-6 - 7 = -13
Therefore, x = -13.
Now, we plug in -13 for x in the first equation:
5 × (-13) = -65
⇒ -65 - 4y = 9
We add 65 on both sides:
→ -4y = 74
Finally, we divide both sides by -4:
y = -18.5 or -18 1/2
Answer Recap: x = -13, y = -18.5 or (-13, -18.5)
