A = 6

4/x - 1 + 6/3x +1 = 15/3x + 1 4/x - 1 + 2/x +1 = 5/x + 1 4/x + 2/x - 5/x = 1 + 1 -1 1/x = 1 x = 1

9A:2 - 1 - 1 + 1 - 1 + 3 - 2 + 6 = 7The answer is seven.

They are: minus 1 and plus 1

15 (times 2, plus 2, minus 1)

-7--1=6. A double minus makes a plus.

(2+1+1)/(3+6+6) = 4/15.

2 - 1/6 = 15/6
