Question

3 is subracted from a number is equal to 12​

Answer 1

In context to question it is asked the value of number obtained if it is substract from 3

let us assume x= number

now  $x-3=12\\x=12+3\\x=15$

so 15 is the number

proof =$15-3=12$

hence finally concluded that 15 is the number.

Answer 2

Here it is given that when 3 is subtracted from a number gives 12

W have to find the number

Let the number be x

Then the condition can be algebraically represented as

x - 3 = 12

We will solve this equation to find the value of x

x - 3 = 12

    x = 12 + 3

    x = 15

Hence, the number will be 15
