Verified Answer :

-6(2+a) = -48
Distributive property
-12 -6a = -48
Add 12 to both sides
-6a = -36
Divide both sides by -6 and you get a= 6

Answer with explanation:

The given equality or expression in one variable is,

⇒  -6×(2+a)= -48

⇒ -6×(2+a)= -6× 8

Dividing both sides by , -6 we get

⇒ 2+a=8

Subtracting , 2 from both sides

⇒2+a-2=8-2

⇒a=6
