Question

Given: x + y = 6. If x ∈ {-15, -6, -1}, then which of the following sets of ordered pairs are solutions? {(-15, -21), (-6, -12), (-1, -7)} {(-15, 21), (-6, 12), (-1, 7)} {(-15, 21), (-6, 12), (-1, -7)}

Answer 1

Answer:

X+Y=6

Put x=(-15)

Getting, Y=21

Put x=(-6)

Y=12

Put x=(-1)

Y=7

So, {(-15,21),(-6,12),(-1,7)}

Is the answer.
