Answer:
The answer to your question is: y = 7
Step-by-step explanation:
Find y when x = -5
-3x – 3y = -6
-3(-5) - 3y = -6
15 - 3y = -6
- 3y = -6 - 15
-3y = -21
y = -21/-3
y = 7
-33/4 or -8 1/4
Make similar terms:
-5/4 - 28/4: then solve
-5 - 28 = -33: put over 4
-33/4: simplify
-8 1/4
We need to see the "given system".
110=50+7(x)
