Is (8, -1) a solution of the system, 2x + 3y = 13 and x - y = 9?


Is (-2, -5) a solution of the system, 3x + 2y = 4 and 2x - 5y = -29?

Graph the two equations to solve the system. What is the ordered pair solution?
x + y = 6 and x - y = 4


Graph the two equations to solve the system. What is the solution?
1/2 x - 2y = 4 and 4y - x = -8

Answer 1

For the first two, sub the values of x and y into each equation, both equations must work!
The other two you need to graph and see where they intersect
