If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the first equation is substituted into the second equation. 12x – y = –4 4x – 3y = –6

Question

anonymous · Answer

2x – y = –4
4x – 3y = –6
Those are our equations.
We can solve for y on the first equation:
2x – y = –4
We add y both sides--->2x=-4+y
We add 4 both sides--->2x+4=y
y=2x+4
How do we continue now?
