Answer 1

Answer:

9

Step-by-step explanation:

Given -3 (7 - x) = 6

Opening brackets

=> - 21 + 3x = 6

=> 3x = 6 + 21

=> 3x = 27

On Dividing both sides by 3

=> x = 9

So value of x is 9

Answer 2

Given: The equation is$-3 (7 - x) = 6$.

We have to solve the above equation.

• By using the concept of equation shifting, we are solving the above equation.  
• For this, we will separate the variables on one side and the constant on another side.  
• Then, we will simplify the equation.

We are solving in the following way:  

We have,

The equation is$-3 (7 - x) = 6$

$=>-21+3x=6\\=>3x=6+21\\=>3x=27\\\\=>x=\frac{27}{3} \\\\=>x=9$

Hence, the solution of the above equation is$9$.
