Answer:
one solution
Step-by-step explanation:
Given two equation
y = -x+4 ... (1)
x+2y = -8 ...(2)
Substituting equation (1) into (2), we will have;
x+2(-x+4) = -8
Opening the bracket up
x-2x+8 = -8
-x = -8-8
-x = -16
x = 16
Substituting x = 16 back into equation 1:
y = -16+4
y = -12
This shows that the linear equation has one solution (16,-12)
