The answer is 20 because you dive it
Answer:
(-11, -12)
Step-by-step explanation:
we need one variable to x out
on the note of x, lets cancel out the xs
6x+3y=-102
3x+y=-45 < same as 6x+2y-90
6x+3y=-102
-
6x+2y=-90
y=-12
substitute y in
3x-12=-45
3x=-33
x=-11
(-11, -12)
Please give brainliest :)
12x-5(x+4)=-20
12x-5x-20=-20
12x-5x=-20+20
7x=0
X=0
Y=0+4=4
