Question

Solve 3n-6=21. Find n​

Answer 1

Here we are given an equation 3n - 6 = 21

We have to solve this equation for the value of n

In order to solve this equation, we will use transposition to solve the equation

So, 3n - 6 = 21

            3n = 21 + 6

             3n = 27

                n = 27/3

                 n = 9

Hence, the value of n will be 9

Answer 2

Answer:

The value of n$=9$

Step-by-step explanation:

As per the data in given equation

In above question it is given that

We have find the value of given expression

Given the data in question 3n-6=21.

Hence, for solving the above equation, we will solve it by separating the like terms at one side.

So, we will shift 6 from LHS to RHS the sign will change from negative to positive,

As we get,

$3n-6=21\\3n=21+6\\3n=27$

divide by $3$

$n=\frac{27}{3} \\n=9$

Hence the required value of n$=9$
