Question

The difference between two numbers is 7. If the smaller number is 7 find the other number

Answer 1

Hint: Smaller number is7

Answer:

The another number is 14

Step-by-step explanation:

14-7=7

Answer 2

Answer:

The other number is 14.

Step-by-step explanation:

Given,the difference between two numbers is 7.

Let two numbers be x and y.

So,The difference between x and y is 7.

Therefore,$x - y = 7....(1)$

It is also given that smallest number is 7.

So,$y = 7$

We are putting value of y in equation (1) and get,

$x - 7 = 7 \\ x = 7 + 7 \\ x = 14$

Therefore value of the other number is 14.

This is a problem of Algebra.

Some important Algebra formulas:

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
