Answer:
<em>x = -10, and y = -1</em>
Step-by-step explanation:
5x - 2y = -48
2x + 3y = -23
First equation times -2: -10x + 4y = 96
Second equation times 5: 10x + 15y = -115
Add the last two equations: 19y = -19
y = -1
Substitute 1 for y in the first original equation.
5x - 2y = -48
5x - 2(-1) = -48
5x + 2 = -48
5x = -50
x = -10
Solution: x = -10, and y = -1
