X/-4=3/4First, let's work on the left hand side of your equation, the X/-4
This means, for instance, to see if it can be simplified at all.

Sorry, can't divide by zero! Stop! Everything below this line is wrong.
To divide X by 1The X just gets copied along in the numerator.The answer is XX/ evaluates to XX/-4 evaluates to X-4So, all-in-all, the left hand side of your equation can be written as: X-4Now, let's work on the right hand side of your equation, the 3/4 
3/4 evaluates to The right hand side of your equation can be written as: So with these (any) simplifications, the equation we'll set out to solve is:
X-4 =
Move the X to the right hand side by subtracting X from both sides, like this:
From the left hand side:
X - X = 0
The answer is -4
From the right hand side:
The answer is

Now, the equation reads:
-4 =
Move the -4 to the right hand side by adding 4 to both sides, like this:
To the left hand side:
-4 + 4 = 0
The answer is 0To the right hand side:
 + 4 =
The answer is
Now, the equation reads:
0 = 
To isolate the a, we have to divide both sides of the equation by theother variables
around the a on the left side of the equation.
The last step is to divide both sides of the equation by 0 like this:

Sorry, can't divide by zero! Stop! Everything below this line is wrong.
0 ÷ 0 = 1To divide by 0divide each term in by 0 term by term.

 ÷ 0 = 1
Sorry, can't divide by zero! Stop! Everything below this line is wrong.
To divide X by 1
The X just gets copied along in the numerator.The answer is X-X ÷ 0 = XThe solution to your equation is:
1 = 1+X

x = 3
-4    4

By cross multiplication
4x=-12
x=-12/4
x=-3

Hence the value of x is -3
