Question

$180 is to be split between you and your friend, with your friend receiving $15 less. how much will each of you receive?

Answer 1

I assume the $180 is being split 50/50. In this case, let x=180, the amount to be split. For your friend, it would be 0.5x-15. For you, it would be 0.5x+15.

Answer 2

This is the way I look at the problem.

Let x = your share
Then x-15 = friend's share

x + (x-15) = 180
x + x - 15 = 180
2x - 15 = 180
2x = 195
x = $97.50 This is your share

x - 15 = $97.50 -15 = $82.50 This is friend's share

Therefore, you receive $97.50 and your friend receives $82.50
