Answer: x= -6

Explanation:

The given equation :
9x = 3x- 36

To solve for x , We first subtract 3x from both the sides m, we get


9x-3x = 3x-36-3x

Now, Simplify


6x = -36

Divide both sides by 6 , we get


(6x)/(6)=(-36)/(6)

Now, Again Simplify


x=-6

Hence, the value of x in the given equation is x= -6

Answer:
x=-6

Explanation:

In order to solve for "x", we must remember the following properties:

  • The Subtraction property of Equality states that:

If
a=b, then
a-c=b-c

  • The Division property of Equality states that:

If
a=b, then
(a)/(c)=(b)/(c)

Therefore, knowing these properties, we can solve for "x" to find its value.

First, we need to subtract
3x from both sides of the equation. Then:


9x-(3x) = 3x - 36-(3x)\\\\6x=-36

And finally, we can divide both sides of the equation by 6. Then we get:


(6x)/(6)=(-36)/(6)\\\\x=-6
