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 = 0The answer is -4From 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 = 0The 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.

Sorry, can't divide by zero! Stop! Everything below this line is wrong.

÷ 0 = 1

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 X-X ÷ 0 = XThe solution to your equation is:

1 = 1+X

__x__=

-4 4

By cross multiplication

4x=-12

x=-12/4

x=-3

Hence the value of x is -3
