Question

3) If sum of two number is 35 and one of them is 23. Form an equation for finding another number​

Answer 1

We are given that the sum of two numbers is 35

Also, one of the two numbers is 23.

We have to make an equation for finding another number​

So, let us assume the other number be x

Then, x + 23 =  35

The equation will be x + 23 = 35

On solving, x = 35 - 23

                      = 12

The value of x comes out to be 12

Answer 2

Given: The sum of two numbers is $35$and one of them is$23$.

We have to find the missing number.

• By using the concept of equation shifting, we are solving the above  equation.  
• For this, we will separate the variables on one side and the constant on  another side.  
• Then, we will simplify the equation.

We are solving in the following way:  

We have,

The sum of two numbers is $35$and one of them is$23$.

Let assume the missing number will be$x$.

From the given statement we can write:

$\Rightarrow x+23=35\\\Rightarrow x=35-23\\\Rightarrow x=12$

Hence, the missing number will be$12$.
