Answer:
the solution is (2, -6)
Step-by-step explanation:
Substitute the second equation into the first, replacing y in the first:
2x - (-4x+2) = 10
Simplifying, we get:
2x + 4x - 2 = 10, or:
6x = 12, which yields x = 2.
Substituting 2 for x in the second equation yields y = -4(2) + 2 = 0, or y = -6
Then the solution is (2, -6).

Answer:
Answer:
Option 1, by $851.70
Step-by-step explanation:
Option 1 total:
$8000 + $765.44*5*12 = $53926.40
Option 2 total:
$8000 + $626.25*4*12 + 0.38*$43995 = $54778.10
The difference:
$54778.1 - $53926.40 = $851.70
As we see the option 1 is cheaper by $851.70
