    Forming equations

    I have 2 math problems that I really don't HAVE to do but I won't learn if I don't. I've tried to figure these out for days and I think I'm just plain stuck. I understand the questions and I could solve them on my own but it asks for me to form an equation that can be used to solve the questions and I just can't come up with it. If someone could help me with this and possibly let me know how they came up with it, I would be very grateful.

    Form an equation and then solve it to answer each question. Make a table to organize the data.

    1. Commissions. A salesman receives a commission of $3 for every pair of dress shoes he sells. He is paid $2 for every pair of athletic shoes he sells. After selling 9 pairs of shoes in a day, his commission was $24. How many pairs of each kind of shoe did he sell that day?

    2. Mover's pay scale. A part-time mover's regular pay rate is $60 an hour. If the work involves going up and down stairs, his rate increases to $90 an hour. In one week, he earned $1,380 and worked 20 hours. How many hours did he work at each rate?

    Thank you very much for taking a look at this. Have a nice day!

    1) Suppose he sells x pair of dress shoes. How many athletic shoes does he sell? 9 - x

    He gets 2 * x dollar plus (9 - x) * 3 dollar, and the total is 24 dollars.

    Maybe that will ease things up?
