Question

When 9 is added to two times a number we get 67 the number is

Answer 1

Answer:

Answer: we will get 9x−2=67. Let us transpose 2 from the left-hand side of the equation to the right-hand side to get 9x=67+2=69

Answer 2

Given:

When 9 is added to two times a given number we get the new number as 67.

To Find:

The original number.

Procedure:

The given question can be solved by using the concept of simple algebra.

1. It is given that when 9 is added to twice a given number, we get 67 as the new number.

• let the original number be x.

2. When 9 is added to twice the original number the expression becomes, 2x+9. ( Since x is multiplied by two and then it is added by a value of 9).

3. It is further mentioned that this expression is equal to the value of 67.

4. The value of x can be obtained by equating the expression and the given value because both of them are equal.

5. It is a linear equation with 1 variable which can be directly solved using basic mathematical operations.

=> 2x + 9 = 67,

=> 2x = 67 - 9,

=> 2x = 58,

=> x = (58/2),

=> x = 29.

Therefore the actual number is 29.
