Question

Verify your solution by substituting the values into each of the original equations. Show your work.

Answer 1

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.

Answer 2

2(2)-4=0

-2+2=0

0=0
