Answer:
15, 6 and - 3
Step-by-step explanation:
Given x - y = 3 , then
(a)
5(x - y) = 5(3) = 15
(b)
2x - 2y ← factor out 2 from each term
= 2(x - y) = 2(3) = 6
(c)
y - x ← factor out - 1 from each term
= - 1(x - y) = - 1(3) = - 3
Right now, x is only equal to two. Square both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, ...
