Question

(1) Two numbers differ by 3. The sum of twice the smaller number and thrice
the greater number is 19. Find the numbers.​

Answer 1

Answer:

Define x.

Let one of the number be x.

Let the other number be (x + 3).

Solve x.

2x + 3(x + 3) = 19

2x + 3x + 9 = 19

5x + 9 = 19

5x = 19 - 9

5x = 10

x = 10 / 5

x = 2

Find the numbers.

One number = x = 2

Other number = (x + 3) = (2 + 3) = 5

Hence, the numbers are 2 and 5.
