The best way to do word problems is first make sure you understand all the words in the problem. Then write down what is known.
For example, in this problem we know the pipe is 90 inches that needs to be cut into 2 pieces with one piece 20 inches longer. Let's show the shorter piece being x and the other piece being x+20. Now we can form an equation like this:
x+(x+20)=90 Combine like terms we get:
2x+20=90 Subtract 20 from both sides gives us:
2x=70 Divide both sides by 2 gives us:
x=35
Now we know the shorter pipe is 35 inches and from here you can figure the length of the longer pipe.
