Question

Without graphing or solving either system of equations explain how you know what the solution to the system is.

Answer 1

x = 5

y = -1

Step-by-step explanation:

from second equation,

• y = -2 + 1
• y = -1

by putting the value of y in first equation

• y = -x + 4
• -1 = -x + 4
• -x = -1 -4
• -x = -5
• x = 5

x = 5 and y = -1
