Answer:

The equation holds for x = - 21,


(x = -21)

Explanation:

To find the value of x that makes the eqution true, we have to solve for x,

solving,


(1/7)x -3=-6

adding 3 on both sides,


(1/7)x-3+3=-6+3\\(1/7)x=-3

Multiplying by 7 on both sides,


7(1/7)x=(7)(-3)\\x=-21

Hence x = -21

Answer: x = -21

Explanation:

Our task is to figure out what value of x makes 1/7x - 3 = -6 true.

First, we add 3 to both sides:


\cfrac{1}{7} x=-6+3


\cfrac{1}{7} x=-3

Next, multiply both sides by 7.


x=-3*7


x=-21

Therefore, the value of x that makes it true is -21.
