What is the solution of the system?
4x-y=-3
6x-y=-8

6x - y = -8
y = 6x + 8 - not plug this in the first equation

4x - y = -3
4x - (6x + 8) = -3
4x - 6x - 8 = -3
-2x = -3+8
-2x = 5
x = 5/(-2)
x = -5/2

Now we can solve for y.
As we said before, y = 6x + 8
y = 6* (-5/2) + 8
y = -15 + 8
y = -7

{x,y} = {-5/2,-7} is the solution to the system

7.3

step-by-step explanation:

81+30=111180 minus 111=691/2×19=9.569÷9.5=7.263157895~7.3

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2
