The age of a man is 10 years more than three times his brother's age.
m = 3b + 10
:
Find the age of each if 5 years from now he will be 4 years more than twice his brother's age.
m + 5 = 2(b+5) + 4
m + 5 = 2b + 10 + 4
m = 2b + 14 - 5
m = 2b + 9
Replace m with (3b+10)
3b + 10 = 2b + 9
3b - 2b = 9 - 10
b = -1; obviously this is not a valid problem
