I thank those helping me with these word problems. I just can't seem to get them locked down in my memory. hoping the formula is not the same for all my last ones, as they don't seem like it? Pat is 17 years older than his son Patrick. In 6 years Pat will be twice as old as Patrick. How old are they now? I try to read this but I get x+17+6 but even if this is a start I then get lost.

Let Pat's present age be x and Patrick's present age be y. Then Pat's age in six years is x + 6, and Patrick's age in six years is y + 6. x = y + 17 (x + 6) = 2 * (y + 6) Last edited by skipjack; March 16th, 2016 at 06:37 AM.

Let us assume Patrick's present age to be "a" years. Pat is 17 years older than Patrick, which means Pat's present age is "a+17" years. After six years, both will grow 6 years older (obviously). Patrick is "a" years old now. So, after 6 years, Patrick's age will be "6 + a" years. Pat is "a + 17" years old now. So, after 6 years, Pat's age will be "6 + (a+17)" years. Quote:
So, 2×(6+a) = (6+a+17) Solving for "a", we get "a = 11" So, Patrick's age is 11 years. Pat's age is "a+17" years and "a" is 11, so Pat's age is 11 + 17 = 28 years. I hope that your brain will not overload and shut down any more.
