Question

When 5 times of a number when is decrease by 10 it's gives 50.Find the number​

Answer 1

Answer:

the number = 12

Step-by-step explanation:

let the number be x

We know LHS (left hand side ) should be equal to RHS ( right hand side )

5x - 10 = 50

we will add 10 on both sides

5x - 10 + 10 = 50 + 10 ( - 10 + 10 = 0 )

5x = 60

(we will take 5 to RHS and it will convert into devision)

x = 60 ÷ 5 ( 60 ÷ 5 = 12 )

x = 12

CHECK :

5 × 12 - 10 = 50

Answer 2

To find : missing number  

Given  : When $5$ times of a number is decrease by $10$ it gives $50$ .

Solution :

• According to question we are given that ,when $5$ times of a number is decrease by $10$ it gives $50$ .  
• Let , $x$ be the missing number .
• Therefore , according to given data in the question we write given condition as $5x - 10 = 50$
• 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,

            $5x - 10 = 50 \\5x = 50 + 10 \\x = \frac{60}{5} \\x = 12$

Hence , number is $12$ .
