Question

Ron bought some toy cars at a garage sale. He gave 5 cars to his sister and had 2 cars left. Which equation, when solved, will tell how many cars Ron bought at the garage sale?

Answer 1

Alright, so let's call the number of cars he buys "x" So we know he gives 5 to his sister, so we have to subtract 5 from the total amount, then we know there is 2 left.

So

X-5=2

X=7

He bought 7 Cars.
