Ages 2t and t today
2t-4=3%28t-4%29
2t-4=3t-12
t=16------Jim
-
2t=32-----Tom
Jim and Tom are NOT 16 and 32. Get correct answer from someone who knows what they're doing.
Ages 2t and t today
2t-4 = 3*(t-4)
2t-4 = 3t-12
t = 8 ------Tom
-
2t = 16 ------Jim
Answer. Tom is 8 years now. Jim's age is 16 years.
Solved ( correctly ! ).
Now compare it with the answers by @josgarithmetic, who gives Jim 16 and Tom 32.
Be aware : The solution by @josgarithmetic is T O T A L L Y W R O N G.
------------------
@josgarithmetic is VERY well known (or better to say, very badly known, unfortunately) in this forum,
for his inability to solve problems correctly and to make calculations accurately.
So be very careful when you obtain "solutions" from him.
In half of all cases (if not at most cases) they are wrong.
Do not trust him and always wait for reaction of other tutors.
In the normal school environment he would be fired in the second day.
I think about thousands of visitors and students who do understand almost nothing in Math and who were misguided
by his false and wrong quasi- and pseudo-"solutions".
