Help me solve these Algebra 2 problems

I really don't get it....

Solve each equation:
4(square root ) of x+1= 3(square root of x+2

(x-5)1/3=3


2(x-50)1/3=-10


Please help me! I don't get it, please!! I need help... I'm really slow in math.

1) 4( square root) of x+1 = 3(square root) of x+2
Square both sides.

[4(square root) of x+1]^2 = [3(square root)of x+2]^2
16 (x+1) = 9(x+2)
16x + 16 = 9x + 18
7x = -2
x = -2/7

2) x-5 / 3 = 3
x - 5 = 3 x 3
x - 5 = 9
x = 14

3) 2(x - 50) / 3 x -10 = 1
2(x - 50) / -30 = 1
x - 50 / -15 = 1
x - 50 = -15
x = -15 + 50
x = 35

Hope this helped.
