how do i do this math problem ? what is my age ? add my age , plus half of it , plus a third of it , plus 3 times three . the results is 6 score and ten , what is my age ?

just start putting the words into symbols. If your age is a,
(a + a/2 + a/3 + 3)*3 = 6*20+10
(11/6 a + 3)*3 = 130
11/2 a +9 = 130
11/2 a = 121
a/2 = 11
a = 22 
Bill is twice as old as Sue. Jim is four years older than Sue. Together their ages add up to 12 years.

Twice Brayton's age increased by 5 resuts in 49
