Answer:
The solution is: x = -5.2, y = 11.2
Explanation:
We are given the following system of equations:
-7x-2y = 14
6x + 6y = 18
Simplifying the second equation by three, we have that:
x + y = 6
y = 6 - x.
Replacing in the first equation:
-7x - 2(6 - x) = 14
-7x - 12 + 2x = 14
-5x = 26
5x = -26
x = -5.2
y = 6 - x = 6 - (-5.2) = 6 + 5.2 = 11.2
The solution is: x = -5.2, y = 11.2
