x=21/3

x=7

Answer 2

Answer:

=> The value of x is 7.

Step-by-step explanation:

Given that:-

$3x-2=19$

To find:- The value of the expression:

Here we will use the transposition method.

As we have,

=> $3x-2=19$

Now add both sides by $2$, we get

=> $3x-2+2=19+2$

Simplifying it further, we get

=> $3x = 19 + 2$

Add the numbers,

=> $3x = 21$

Divide both sides by $3$, we get

=> $x = 7$

Hence, the required solution is 7.
