Answer by greenestamps(13200) (Show Source): You can put this solution on YOUR website!
(1) define a variable
let x = your age (now)
(2) use that variable to define expressions for the other numbers in the problem (your age 16 years from now; and your father's age now, and 16 years from now)
2x+12 = your father's age now
x+16 = your age 16 years from now
(2x+12)+16 = 2x+28 = your father's age 16 years from now
(3) Use those expressions to write an equation using the given information
"In 16 years, my father’s age will be 30 years less than three times my age."
Rewrite that to put it exactly in terms of the expressions you have defined:
My father's age 16 years from now will be (is) 30 less than three times my age then (16 years from now):
2x+28 = 3(x+16)-30
(4) solve using basic algebra
I leave that to you....
