3(-2a-4)+3a
Help please

-3a-12

Step-by-step explanation:

start by distributing ( or multiplying) the 3 into the numbers in the parenthesis but NOT to 3a (bc it's not in the parenthesis):

3(-2a-4)+3a —> -6a-12+3a

**Distributing the 3 into the parenthesis simplifies the expression in order to make it easier to solve.

Then you can start combining like terms (-6a and 3a):

-6a-12+3a —> -3a-12

-3a-12 is your answer.

**Just a side note, some students may think they have to keep going because they think that you have to divide the 3 from both numbers to simplify it completely, but you don't. Because this isn't an equation where you have to solve for 'a', -3a-12 is the furthest you can go with this answer.
