Answer 2

Answer:

=> The value of x is -7.

Step-by-step explanation:

Given that:-

$3x=-21$

To find:- The value of x,

For solving this equation, we have to use the transposition method:

As we have,

=> $3x=-21$

Now divide both sides by 3, we get

=> $\frac{3x}{3}=\frac{-21}{3}$

Simplifying it further, we get

=> $x = -7$

Hence, the required solution is -7.
