    The length of a train car is 50.6 feet. This is 5.8 feet less than 6 times the width. What is the width?

    5.8 feet less than 6 times the width is an algebraic expression:
    6w - 5.8

    We set this equal to the length of 50.6
    6w - 5.8 = 50.6

    Add 5.8 to each side:
    6w - 5.8 + 5.8 = 50.6 + 5.8

    Cancel the 5.8 on the left side:
    6w = 56.4

    Divide each side by 6:
    6w/6 = 56.4/6

    Typing this problem into the search engine, we get w = 9.4.
