Question

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

2x+2y=11

2x+3y=13

2x-y=2

2x-2y=5

Answer 1

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
