Question 169622: Solve each system by substitution. Determine whether the equations are independent, dependent or inconsistent:
y= -4x-7
y= 3x Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! y=3x
y=-4x-7
3x=-4x-7
3x+4x=-7
7x=-7
x=-7/7
x=-1 ans.
y=-3*-1
y=-3 ans.
Proof:
-3=-4*-1-7
-3=4-7
-3=-3
