An example could be: 3x-2 = x-6 and so the variable x = -2

You just write, "No Solution."

You have to decide what the meaning of the equation will be.

First, write it in a mathematical equation form:4x=2x+14Next, subtract 2x from both sides2x = 14Divide both sides by xx = 7

You can add or subtract the same number to both sides of an equation without changing the solution, so adding 4 to both sides yields |5x| = 20. Since 5 is positive, it can be moved outside the absolute value: 5*|x| = 20. You can multiply or divide both sides of the equation by any non-zero number, so you can divide both sides by 5 to get |x| = 4.So x is either 4 or -4, will solve your equation. If you want to write the equation without using absolute value, you can write a quadratic equation which has solutions of 4 and -4: (x + 4)(x - 4) = 0 --> xÂ² - 16 = 0

If there are two variables, you'll usually need two equations in the two variables, to be able to find a specific solution. How you write the equation depends on the specific problem. In general, it requires some practice, to be able to convert a word problem into mathematical equations.

Simply write that "no solutions are available for <equation>".

You can write an equation that works in forward and reverse by setting the same variables on either side. Alternatively you can set offsetting variables on each side which will also create the same results.

I assume you want an equation with a solution of 212. Just write: x = 212 If you want something more fancy, do something to both sides of the equation - this is basically the opposite of what you do to solve an equation. For example, you can multiply both sides of the equation by some number (the same on both sides, of course), add the same number to both sides, square both sides (note that this will most likely add additional solutions, that are not solutions to the original equation), etc. If you already know a bit about more advanced math, you can take logs or antilogs on both sides, take sines or inverse sines on both sides, etc. (this, too, may introduce additional solutions).
