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)
