The ordered pair (5,1) satisfied which of the following equations:

2x+2y=11

2x+3y=13

2x-y=2

2x-2y=5

Replace X and Y in the given equations and see if they are true:

2 (5) + 2 (1) = 10+2 = 12 ... does not equal 11 So this in not right.

2 (5) + 3 (1) = 10 + 3 = 13 this is correct.

The answer would be: 2x+3y=13
