Answer 1

$\huge\tt\colorbox{pink}{Answer}$

$3x + 12 = 72$

$3x = 72 - 12$

$3x = 60$

$x = \frac{60}{3}$

$x = 2$

Answer 2

Answer:

=> Hence, the value of x is 20.

Step-by-step explanation:

In context to questions asked

We have to find the value of x,

The given expression,

$3x + 12 = 72$

Here we will use the transposition method.

Now, transposing $12$ on the right side:

=> $3x = 72-12$

Subtract the numbers, we get

=> $3x = 60$

Divide both sides by $3$,

=> $x =20$
