[Namine]

It is 70 because 2n > 70 + n and 70 + n < 140`are the wrong conditions according to the question.

I have:

2n - 70 = 140 - n

which is similar to what wira wrote to begin with.

"the number whose double exceeds 70 by as much as the number itself is less than 140."

Bolded part signifies where the equal sign is, and got nothing about inequalities. Wira already explained the 2 sides of the equality sign. The wording is certainly not best, but this would be how to interpret the question.
