Answer:

a=4

Step-by-step explanation:

To solve, we need to get the variable, a, by itself. To do this, we need to reverse what is being done to a.

4(2+a)=24

Divide both sides by 4, since it is being multiplied by 2+a

4(2+a)4=24/4

2+a=6

Subtract 2 from both sides since it is being added to a

2-2+a=6-2

a=4
