Part 1: . if you were solving a system of equations and you came to a statement like 4 = 4, what do you know about the system? . part 2: . solve the following system and show all of your work.. 3y − 2x = 11. y + 2x = 9.

If we are given or come up with a statement of 4 = 4, then the equation is true, This is because the left hand side and the right hand side are equal. Solving y − 2x = 11 and y + 2x = 9, we just add the two equations to yield 2y = 20 or y equal to 10. x is equal to -1/2. The coordinates are (-1/2, 10)
