Question

The difference between 13 and a number is 4 more than twice the number

Answer 1

Answer: 3

Explanation:

Let the number be 'a'.

Since the difference between 13 and a number is 4 more than twice the number, then 13 - a = 2a + 4

⇒ 13 - a = 2a + 4

2a + a = 13 - 4

3 a = 9

a = 3

∴ the number is 3
