Question 92525: I am lost on this one
Solve the system by addition or substitution.
20x � 5y = �12
y = 4x + 3
A) (3, 4) B) (-3, -4) C) (3, -4) D) Inconsistent system (No solution)

Plug in y = 4x + 3

Distribute

Add 15 to both sides

Combine like terms. Since this is never true for any x, there are no solutions.

So the system is inconsistent. This means the answer is D)
