each year john contributes $400 less than twice as much money as jim to charity. if together they contribute $950, how much does each contribute?

Question

Im stuck on this problem for ages please help!!!!!!!!!

Answer 1

Let x = Jim's contribution

Let 2x - 400 = John's contribution

x + 2x - 400 = 950

3x = 1350

x = $450 - Jim's contribution

2x - 400 = 2(450) - 400 = $500 - John's contribution
