Question

Of two numbers, one is 7 more than the other. Find the numbers if their sum is 21

Answer 1

Hi there! The smallest number is 7 and the largest number is 14.

Let the smallest number be represented by X.
The largest number is therefore equal to X + 7.

Now we can set up and solve an equation.

`x + x + 7 = 21`

Collect terms

`2x + 7 = 21`

Subtract 7 from both sides.

`2x = 14`

Divide both sides by 2.

`x = 14 / 2 = 7`

Hence, the smallest number is 7 and the largest number is 7 + 7 = 14.

Answer 2

it would be 14 and 7.
