How to solve this system using substitution
3x-6y=-6
-2x+y=4
2 answers:
Your x and y intersection is: (-2,0).
Answer:
Step-by-step explanation:
3x-6y=-6..........(1)
-2x+y=4............(2)
Making y as subject in (2)
y = 2x + 4.......(3)
Substituting (3) into (1)
3x - 6(2x + 4) = -6
3x - 12x - 24 = -6
-9x = -6 + 24
-9x = 18
x = 18/-9
x = -2
Substitute x = -2 into (3)
y = 2x + 4
y = 2(-2) + 4
y = -4 +4
y = 0
