Answer:
First, you have to substitute your x and y.
This looks like
(-6)(-2 - 12) because you multiplied (-2)(1) and (-4)(3)
Then, you have to do what's in the parenthesis because of order of operations.
(-6)(-14)
The answer is 84 I believe.
the volume is 420 cubed inches
if you mean that 3x+3=0 then x should equal 0
8
Step-by-step explanation:
8+12+4+3+14+1+9+13=64, 64/8=8
x=-2 y=0
put the second equation in to the first one
-2x+x+2=4
-x=2
x=-2
y=-2+2=0
