Answer 1

Answer:

  8

Step-by-step explanation:

Let n represent the number.

  2n+3 . . . . "doubled, then increased by 30"

  3n -5 . . . . "five less than three times the number"

These two results are equal, so we have ...

  2n +3 = 3n -5

  8 = n . . . . . . . . . . add 5-2n

The number is 8.
