Math has always been really hard for me. I always need help, and I have no one around the house to help me. Please help!

Example A: 2n + 3 = 13
Example B: n + 3 = 13

Which example is a one-step equation?

How is solving a two-step equation like solving one-step equation? How is solving them different?

B is a one-step equation, because it only takes one step to solve it for n.  Your one step would be to subtract 3 from both sides and you have the equation in terms of n.

imstuck · Answer

Solving a two-step is like solving a one step because the end result will be the same...putting the equation in terms of a certain variable.  They are different because two-step equations often take some mathematical "gymnastics" to get the desired variable alone.  Like taking a square root of a number or dividing it or multiplying it...the list is endless.

I have one more:
Write an equation that you could solve using these steps:

Add 7 to both sides. Then, divide both sides by 4. 

Explain how you know your answer is right.
