Given the equation:
3 (2x + 12) = 24
Determine the value of x.
Solution:
In order to determine the value of x, we simply need to distribute 3 to each value inside the parenthesis first.
3 ( 2x + 12 ) =24
6x + 36 = 24
Transpose 36 on the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
6x = 24 - 36
6x = -12
Divide both sides by 6 in order to cancel out 6x, leaving behind x.
6x/6 = -12/6
x = -2
Final answer:
x = -2
