Answer:
x = -2 y = 3
Step-by-step explanation:
Equation 1: y = -x + 1
Equation 2: 23 = 5y -4x
Take and plug in what y equals (from equation 1) into equation 2
23 = 5(-x+1) - 4x
23 = -5x + 5 - 4x
23 = -9x + 5
18 = -9x
x = -2
Then plug the -2 in to the first equation for x
y = -(-2) + 1
y = 2 + 1
y = 3
