10(1/2x + 5) = 7
That's the way to write the description of that equation. Good luck!!
Answer:
Yes
Step-by-step explanation:
Yes
C because you have to substitute so 1=-2(-2)-3
Answer:
x = -3, y = 2
Step-by-step explanation:
x - y = -5
x = -5 + y
Let's put this into the other equation
(-5 + y) + y = -1
-5 + 2y = -1
2y = 4
y = 2
Now we can solve for x by plugging y into either equation
x + (2) = -1
x = -3
