Manipulation of Formulae-Algebra

Please help me to solve: (1) Make x the subject of the formula z=3(y+x) (2) Make x the subject of the formula 2y = 1 - 4 3 x (3) If V = ax2 + b, express x in terms of V, a and b. (4) If V = πr2h find an expression for r. (5) If bd = n(2a + nd) find an expression for d. (6) If r = √x2 + y2 Find an expression for x. (7) If x + a = x + b Find an expression for x. C (8) Given that x = 3 and y = 3m2 . Express y in terms of x.
