12 + 6x = 3(4 + 2x)

Explanation:

This questions is basically telling you to "Factorise the expression"

In order to factorise:

1) Find the Greatest Common Denominator (GCD) for all terms.
GCD of 12 and 6x is 6.

In this case use 3 because 12 div 3=4

2) Put this number outside the bracket:

3(Something will go inside this bracket)

3) Divide each term by the factor 3 and put it inside the bracket:

3(12/3 + (6x)/3) = 3(4 + 2x)
