Respuesta :
x = 1/4
y = -2
______________
Known :
y = -8x
4x - y = 3
Asked:
Use the substitution method to solve the system of equations ?
Answered:
Substitution y
4x - y = 3
4x - (-8x) = 3
4x + 8x = 3
12x = 3
x = 3/12
x = 1/4
Substitution x
4x - y = 3
4(1/4) - y = 3
4/4 - y = 3
1 - y = 3
-y = 3 - 1
-y = 2
y = -2
