Question

Find the number if 20 is taken away from 5 times a number is 30.​

Answer 1

Answer:

Ans is 30 so when we add 20 + 30

then it is equal to 50 which is 5 times of 10

so the final answer is 10

Answer 2

To find : value of missing number .

Given : if $20$ is taken away from $5$ times a number is $30$.

Solution :

• Let, missing number be $x$ .
• According to given data we write condition as  , $5x -20 = 30$  

• Here, we will use the below following steps to find a solution using the transposition method:

1. We will Identify the variables and constants in the given equation.
2. Then we differentiate the equation as LHS and RHS.
3. We take constants at RHS leaving variable at LHS. .
4. Simplify the equation using arithmetic operation as required to find the value of $x$ .
5. Then the result will be the solution for the given linear equation. By using the transposition method. we get,

• $5x -20 = 30$  

        $5x = 30 + 20\\5x = 50 \\ x= 10$

Hence, value of missing number is $10$ .
