Answer:

Concept: Linear System

  • You indicated that it has a solution of (2,0)
  • For two equations to have a solution that means that they cross directly at that point and when plugged in gives a direct answer that equal each other
  1. Lets prove it
  2. y=2(2)-4= 0 Hence true
  3. y=-(2)+2= 0 Hence true
  4. So we can say that (2,0) is a solution that satisfies both equations.
