I misread the question and voted wrong. I think it oughta be
I used these equations where x is the dad's current age and y is the son's current age. I think I did it correctly. --- "You must gather your party before venturing forth" "Go for the eyes Boo! Go for the eyes!" ... Copied to Clipboard!

x = older person's current age
y = younger person's current age x = y = Check: 2 years ago, Check: 14 years forward, I kept messing up b/c I forgot to account for the -2 and +14 on the "y side", lol That's why you sanity check the results, to see something's clearly wrong. ... Copied to Clipboard!

No one has voted forThe whole word problem is written poorly. It switches from "I" talking to "you" abruptly to 3rd person (their), and in doing so makes it linguistically unclear if the use of "were" (also a poor choice for clarity) is inferring the past state of 2 years ago or...since it's now a purely a clinical 3rd person narrative, is simply asking in the sense of "what were the ages (now) to make both the past and future conditions possible?" I could see it going either way but logically makes the most sense to be asking what age they are in the present. If you showed all your work and the teacher tried to not give you credit b/c you didn't understand his failed attempt at English, he's a dick. *shrug* ... Copied to Clipboard!

Meaning, whoever can't solve this, never passed 6th grade --- 2020 St. Louis Cardinals did alright ... Copied to Clipboard!

the thing is, if it's a multiple choice question, it's far quicker to trial and error until one or neither fits, solving for x is a waste of time

If the question was multiple choice, then you only had to take each answer given, subtract 2 years from each age, divide the older age by the younger age, and find which gives the answer of three. Since only one of those answers was correct to get 3 you then had to test that answer to make sure that adding 14 years to each age would make the older age twice the younger age. I'll admit that way is a sort of cheat, but you don't need a complex set of formulas to solve it if the question was multiple choice.
