orTo show that 6(x-2) + 12 is equivalent to 6x we will have to equate the expression
6(x-2) + 12 = 6x
6x - 12 + 12 = 6x
6x + 0 = 6x
6x = 6x
So, it can be seen that the two equations are equal
Option A is correct
Option B is also correct because if you substitute 2 into either the left or right equation, you will get 12
Option C is also correct because upon substituting 6 into both equations, you will get 36
Option D is also correct because if either 2 or 6 is substituted, the expression is equivalent
