Solve the following system of equations: 5x + y = 9 3x + 2y = 4 (-2, 5) (1, 4) (2, - 1) (4, - 4)

Multiply first equation by 2:

10x + 2y = 18

Subtract the second equation from this so that the 2y terms cancel:

10x - 3x = 18 - 4

7x = 14

x = 2

Plug into first equation to find y:

5 (2) + y = 9

10 + y = 9

y = - 1

The answer is (2,-1)

Plug each set in until both equations are correct. The answer is (2,-1)
