Answer:
x=7
y= -11
Step-by-step explanation:
3x+4y= -23 equation 1
2y-x= - 29 equation 2
using equation 2 we have:
2y +29 = x equation 3
using equation 3 in equation 1 we have:
3x+4y= -23
3(2y +29) +4y = -23
6y + 87 +4y =-23
10y +87= -23
10y = -23-87
10y = -110
y= -110/10
y= -11
so we have:
2y +29 = x
2(-11) +29 = x
we have:
x= 7
