Answer:

a=-6

Explanation:

In order to solve for a, we must isolate a on one side of the equation.


2(a+5)=-2

2 is being multiplied by (a+5). The inverse of multiplication is division. Divide both sides of the equation by 2.


2(a+5)/2=-2/2


(a+5)=-2/2


(a+5)=-1

5 is being added to a. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.


a+5-5=-1-5


a=-1-5


a=-6

Let's check our solution. Plug -6 in for a and solve.


2(a+5)=-2


2(-6+5)=-2


2(-1)=-2


-2=-2

This checks out, so we know our solution is correct.

The solution to the equation 2(a+5)=-2 is a=-6
