Define x:

Let one of the number be x

The other number is x + 3

Solve x:

2x + 3(x + 3) = 19

2x + 3x + 9 = 19

5x + 9 = 19

5x = 10

x = 2

Find the numbers:

One number = x = 2

The other number = x + 3 = 2 + 3 = 5

Answer: The two numbers are 2 and5

Answer 2

Giving value to x

Let one number be x

So, the other number shall be x + 3

Solving x

2x + 3(x + 3) = 19

2x + 3x + 9 = 19

5x + 9 = 19

5x = 10

x = 2

Finding the numbers

One of the number = x = 2

Another number = x + 3 = 2 + 3 = 5

∴The two numbers are 2 and 5
