Question

Simply The Expression 12+3(7y-8)

Answer 1

First we use the distributive property to eliminate the parenthesis:

$\begin{gathered} 12+3(7y-8)=12+3(7y)+3(-8) \\ =12+21y-24 \end{gathered}$

Now we add similar terms and we get the following:

$12+21y-24=21y-12$

Notice that 21 and 12 are divisible by 3, therefore, we have::

$21y-12=3(7y-4)$

Finally, the simplifed expression of 12+3(7y-8) is 3(7y-4)
