Answer 2

Answer:

=> The value of x is 5.

Step-by-step explanation:

Given that:-

$4x -1 = 19$

To find:- The value of the expression:

Here we will use the transposition method.

As we have,

=> $4x -1 = 19$

Now add both sides by $1$, we get

=> $4x -1+1 = 19+1$

Simplifying it further, we get  

=> $4x = 19+1$

Add the numbers, we get

=> $4x = 20$

Divide both sides by $4$, we get

=> $x = 5$

Hence, the required solution is 5.
