This is an easy question. Here is the solution:

3(x-2)-2x=x-6

3x - 6 - 2x = x - 6

3x - 2x - 6 = x - 6

x- 6 = x - 6

Hence proved that right hand side of the equation is equal to the left hand side of the equation.

3(x-2)-2x=x-6

3x - 6 - 2x = x - 6

3x - 2x - 6 = x - 6

x- 6 = x - 6

Hence proved that right hand side of the equation is equal to the left hand side of the equation.
