B.(-15, -10, 10, 20)
C.(-15, -10, 7, 10, 20)
D.(-15, -12, -10, 2, 7, 10, 20)

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
