Here is the word problem:
A 190-inch board is cut into two pieces. One piece is four times the length of the other. Find the lengths of the two pieces. Find the length of the short piece.
Here is a demo of me working through the problem.
You might be asking yourself where the four parts are? I was focused on explaining in the demo, but on a test we want to be more careful about our presentation of the solution. Here are the four parts of the answer that I want to make sure are on my paper before I turn it in.

- Part 1: Defining the Variable x is the smaller of the two sub-pieces of the board
- Part 2: Writing the Equation, Inequality, or System of Equations x + 4x =190
- Part 3: Writing the Solution to the Equation, Inequality, or System of Equations x = 38
- Part 4: Write the Answer to Your Question The small piece is 38 inches long.
