Answer:

Step-by-step explanation:

This is your equation:

[tex]\sqrt{3x-2}=4[/tex]

To undo that square root, square both sides, giving you:

3x - 2 = 16.  Solving for x gives us

3x = 18 so

x = 6

If you plug 6 back into the equation, the original one, you get that the square root of 16 = 4, which is true.
