Answer 2

Answer: 25.

Step-by-step explanation:

Let the number be a.

Now, according to the conditions,

2a (twice the number) + (increased) 20 = (result) 3a-5 (5 less than three times the number)

2a + 20 = 3a - 5

20 + 5 = 3a - 2a (transporting non variable terms to Left side and a terms to the right side)

25 = a.  

Verification:

2a + 20 = 3a - 5.

2(25) + 20 = 3(25) - 5.

50 + 20 = 75 -5

70 = 70

Hence, Verified.
