Step-by-step explanation:

3x=81

x=81÷3

x=27

so 2x will be

2 × 27

Answer 2

The value of 2x is,

Given : The value of 3x is, 81

To find : The value of 2x

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the value of 2x)

First of all, we have to calculate the values of x. (the value of 2x will be calculated later by multiplying 2 with the value of x)

Now,

3x = 81

x = 81/3

x = 27

So,

The value of 2x will be :

= 2x

= (2 × x)

= (2 × 27)

= 54

(This will be considered as the final result.)

Hence, the value of 2x is 54
