Answer:
x=1, y=-6. (1, -6).
Step-by-step explanation:
y=-6x
-2x-7y=40
------------------
-2x-7(-6x)=40
-2x+42x=40
40x=40
x=40/40
x=1
y=-6(1)=-6
Your answer is A. -56
Hope this helps!
-46 + (-48) = -94
-42 + 46 = 4
Example :
20 + 30.....GCF = 10
10(2 + 3)
The GCF of the number now is 1....because u have basically already factored the GCF out.....leaving only 1 as a factor now
here's another one...
3 + 9...GCF = 3
3(1 + 3)
so the GCF now is 1
