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
