Answer:
8x+6y=48
x+y=7
multiply bottom equation by 6:
8x+6y=48
6x+6y=42
subtract equations:
2x=6
divide 6 by 2:
x=3
therefore:
y=4
The answer is 150 because
5*30
shortcut: 5*3=15
add the zero from the 50
150 is your answer..
You are subtracting -16-4
So I would assume your answer would be C
I hope this answer helps!
