The correct answer is D
Simplify:
6x + 8y - [(12x + 6y) - (4x + 3y) + 2y] - 4xIf 9x2 + 16y2 = 24xy, then find the ratio of ‘x’ and ‘y’, respectively.
- Suppose [a + (1/16a)] = 3, then the value of [16aÂł + (1/256aÂł)] is:
If, 6x + y = 20, and 2xy = 32, and 6x > y, then find the value of 216xÂł â yÂł.

 If x + 1/x = 2, find x⡠+ 1/xâˇ.
(x â 6) 2 + (y + 2) 2 + (z â 4) 2 = 0, then find the value of 4x - 3y + z.
