Question

The sum of twice a number and 13 is less than 19. What is the number?

Answer 1

Let’s call the number we are looking for “x”. The sum of twice a number and 13 is less than 19 can be written as:

2x + 13 < 19

Subtracting 13 from both sides, we get:

2x < 6

Dividing both sides by 2, we get:

x < 3

Therefore, the number we are looking for is less than 3.
