You can put this solution on YOUR website!
Sam = x years
Joe = (3/5)x
after 5 years
sam= x+5
Joe = (3/5)x+5
%28x%2B5%29=%283%2F2%29%2A%28%283%2F5%29x%2B5%29
multiply by 2
2%28x%2B5%29=3%28%283%2F5%29x%2B5%29%29
2x%2B10=3%283x%2B25%29%2F5%29%29
multiply by 5
5(2x+10)=3(3x+25)
10x+50=9x+75
10x-9x=25
x= 25 ===.Sam's age
Joe's age 3/5 * 25 = 15 years
