Liju and Benny had an equal number of pencils at first. Irad had 5 more pencils than Liju. After Benny gave away 10 pencils and Irad gave away 9 pencils, Benny had 2/5 as many pencils as Irad. How many pencils did Liju have?
L = x
B = x
I = 5 + x
______
B = x - 10
I = x - 4
x - 10 = 2/5(x - 4)
x - 10 = 2x/5 - 8/5
5x - 50 = 2x - 8
3x = 42
x = 14
