I need help please.
Solve this proportion for the variable: x+2/x+6=x-4/x-2
Answer Options:
A. x=-10
B. x=7
C. x=10
D. x=-7

%28x+%2B+2%29%2F%28x+%2B+6%29+=+%28x+-+4%29%2F%28x+-+2%29, with x%3C%3E+-+6, or x+%3C%3E+2

(x + 2)(x - 2) = (x + 6)(x - 4) ------ Cross-multiplying

x%5E2+-+4+=+x%5E2+%2B+2x+-+24

x%5E2+-+x%5E2+%2B+2x+=+-+4+%2B+24

2x = 20

x = %2820%29%2F2, or highlight_green%2810%29 (CHOICE C)

You can do the check!!
