If you would like to solve the system of equations, you can do this using the following steps:
2x + 3y = 40
-2x + 2y = 20
____________
2x + 3y - 2x + 2y = 40 + 20
5y = 60 /5
y = 60/5
y = 12
<span>2x + 3y = 40
</span>2x + 3 * 12 = 40
2x + 36 = 40
2x = 40 - 36
2x = 4
x = 4/2
x = 2
(x, y) = (2, 12)
The correct result would be <span>d. x = 2, y = 12.</span>
You're answer should be C: 8.06; 4.03
Hope this helps!
