Question

hmmm...oh I hate these.

2x + 7 = 21
2x = 21 - 7
2x = 14
x = 7

you go into a store and you see some things you want, but you only have $21.
you want (something that costs $7-- just make up something) and you also want some candy. The candy (x) costs $2. How many pieces of candy can you buy without going over your budget of $21 ? By solving the equation, you find out that you can buy 7 pieces.

Does that sound to stupid ??
