For this case we must find the value of the variable "x" of the following equation:

3 (4x + 6) = 21

We apply distributive property to the terms within parentheses:

12x + 18 = 21

We subtract 18 from both sides of the equation:

12x + 18-18 = 21-18

We divide between 12 on both sides of the equation:

12x = 3

$x = \frac {3} {12}\\x = \frac {1} {4}$

$x = \frac {1} {4}$
