y=-x+5
y=2x-4
This is the problem I have to do. Can you use any method for solving systems of equation? Can you also explain the problem?

Since y = - x + 5, and y = 2x - 4, then:
- x + 5 = 2x - 4
- x - 2x = - 4 - 5
- 3x = - 9

, or

y = - 3 + 5 ------ Substituting 3 for x in eq (i)

You can do the check!!
