Multiply first equaton by -1 and add to first
-2x+y=7
<u>4x-y=-4 +</u>
2x+0y=3
2x=3
divide 2
x=3/2
sub
2x-y=-7
2(3/2)-y=-7
3-y=-7
minus 3
-y=-10
negative 1 times both sides
y=10
(3/2,10)
(1.5,10)
B is ansre
The answer is $122.13
Explanation:
610 • 0.32 = 1,105.6
Then you’re going to add everything up:
650 + 260.40 + 260.40 + 16.95 + 11.56 + 10.56 + 17.84
And get =
1,227.73
And you’re going to subtract that with 1,105.6 and get the answer.
