Answer:
y=1.4
x=-1.6
Explanation:
Hi, to solve this system of equations we have to multiply the second equation by 2, and then subtract the first equation to the second one:
4x+y=-5
-2x+2y=6
-4x+4y=12
+
4x+y=-5
__________
5y =7
y = 7/5 = 1.4
Replacing y=1.4 on any equation:
4x+1.4=-5
4x = -5-1.4
4x= -6.4
x=-6.4/4
x=-1.6
