Answer:
(-6,-7)
Step-by-step explanation:
we have:
-3x + y = 11 equation 1
5x -2y = -16 equation 2
using equation 1 we have:
y = 11+ 3x equation 3
using equation 3 in equation 2 we have:
5x -2(11+3x) = -16
5x -2*11 -2*3x = -16
5x -22 -6x =-16
-x = -16 +22
x = -6
so we have:
y = 11+ 3(-6)
y = 11 -18
y = -7
