Question

What is the solution to this equation?

X +8=-3
A. x=-11
B. x= 11
c. x= -5
D. x = 5

Answer 1

A. x= -11

Explanation:

We want to solve for x. Therefore, we must get x by itself on one side of the equation.

x+8= -3

8 is being added to x. The inverse of addition is subtraction. So, subtract 8 from both sides of the equation.

x+8-8=-3-8

x= -3-8

x= -11

Now let’s check our solution. Plug -11 in for x in the original equation.

x+8=-3

-11+8=-3

-3=-3

This checks out, so we know our solution is correct and A. x= -11 is the correct choice.

Answer 2

Option A

Explanation:

x + 8 = -3

x + 8 - 8 = -3 - 8

x = - 11
