Question 1168472: Subject: Consecutive odd integers
Choose three consecutive odd integers such that three times the second decreased by 4 is equal to twice the third increased by 15.
I attempted to solve this problem as follows.
3(x+2)-4=2(x+4)+15
After solving the equation the integers were: 21, 23, 25; however, my book gives me a different answer. I will appreciate your help. Thank you.

Consecutive odd integers, x, x+2, x+4

The translated description,

-------your first of these integers.

They are 21, 23, 25.

.

The condition of the problem is AMBIGOUS. It can be read, translated and interpreted in two different ways. One way is 3(x+2) - 4 = 2(x+2) + 15. The other way is 3(x+2) - 4 = 2*((x+2) + 15). Different equations/translations/interpretations produce different answers.

Therefore, such long formulations in English practically make no sense, because they often are ambiguous.

Not only they are ambiguous --- they often are DANGEROUS.
