Question

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

Answer 1

Answer:

a=-6

Step-by-step 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

Answer:

a=-6

Step-by-step explanation:

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

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