Answer 1

x=-4

Explanation:

So when solving a one-step algebraic equation you need to remember what you do to one side you have to do to the other side. In the problem x + 13 = 9 you need to subtract 13 from both sides to isolate x. So your problem should look like x = 9 - 13. Now all you have to do is solve 9 - 13 which is -4. So x = -4.

I hope this helped.

General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS
• Equality Properties

Explanation:

Step 1: Define equation

x + 13 = 9

Step 2: Solve for x

1. Subtract 13 on both sides: x = -4

Step 3: Check

Plug in x into the original equation to verify it's a solution.

1. Substitute in x: -4 + 13 = 9
2. Add: 9 = 9

Here we see that 9 does indeed equal 9.

∴ x = -4 is a solution of the equation.
