Solve for x:
3x - 4 = 2x + 5
x + y = 4, xy = 2, y + z = 5, yz = 3, z + x = 6 and xz =4, then find the value of x 3  + y 3  + z 3  – 3xyz.
...If √y + (1/√y) = 10, then find the value of y + (1/y).
If (x – 12)3 + (x – 5)3 + (x – 7)3 = 3(x – 12)(x – 5)(x – 7) then find the value of (x2 + 5x...
 If f(x) = 3x² − 7x + 5, find f(2a) − 4f(a).

If a = (√2 - 1)1/3, then the value of (a-1/a)3 +3(a-1/a) is:
If 4x² + y² = 40 and x y = 6, then find the value
of 2x + y?
