If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.

The ordered pair is (6, 3).

7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387

1. x + y = 62. -x + 3y = -2Adding 1. to 2. gives:3. 4y = 4y = 1Substitutuing y = 1 into 1. gives:x + 1 = 6x = 5Writing our ordered pair in the form of (x,y) we have (5, 1).
