just looked it up hehe sorry
4x + 3y = 65
X + y = 18
When you use elimination, multiply the second equation by -3
4x + 3y = 65
-3X -3y = -54
X = 11
X+y = 18
11 + y = 18
Y = 7

Step-by-step explanation:
Y^2-5=31 add 5 to both sides
y^2=36 take the square root of both sides..
y=±√36
y=±6
y=-6 and 6 so B and D is the answer.
