If 5 basketballs and a soccer ball cost $340 and 3 basketballs and 2 soccer  balls cost $260, then how much does 1 basketball cost and 1 soccer ball cost?

5b +s =340     and

3b +2s = 260      Multiply 1sr equation by -2 and add to second equation to get

-7b = -420

b = 60       then   5(60) + s = 340   shows   s = 40         ....you can finish ! smiley
