10% of 88 = 8.8

2.5% of 88 = 2.2

2.2 + 8.8 = 11

88 - 11 = 77

Joe is 10 years older than James and eight years twice Joe’s age will equal three times James eight how old is Joe now.

Lady_Fox [76]

Let James be x years old
Joe = 10 + x
After 8 years
18 + x = 3(x)
18 + x = 3x
18 = 2x
x = 9

Joe is 19
James is 9
