Answer:

I have 488 books in my library. 59 books are taken away, and then 159 books come to the library. How many books does the library have now?               488-59=429 429+159=588

Step-by-step explanation:

2 step problems have two steps, like (1+2)-3=0

What you would use in a 2 step equations is to have more than one operation. Or to do a 2 - step - equation.

You have to simplify a lot of things.

You would use addition or subtraction and then multiplying or dividing.

And finally, you would get the answer for that variable.

For example, 2x+3=3*4

3x+3=3*4

3x+3=12

    -3   -3

--------------

3x=9

x=3
