Question

Solve for a
2(a+5)=-2 Steps too please ❤️

Answer 1

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

Answer 2

a=-6

Explanation:

2(a+5)=-2 Step 1 distribute

2a+10=-2 Step 2 minus 10 on both sides

2a=-12 Step 3 divide but 2 on both sides

a=-6
