You need to be sure the variable denominator does not become zero, where the equation would not be defined.
Two cases in which this can typically happen (there are others as well) are: 1. The equation includes a square. Example: x2 = 25; the solutions are 5 and -5. 2. The equation includes an absolute value. Example: |x| = 10; the solutions are 10 and -10.

204 divided by 2 is 102
An equation of the second degree, meaning it contains at least one term that is squared.

There is no easy way to check this. You need practice in solving equations; anyway, here are a few considerations. First of all, double-check whether you did everything correctly.If done correctly, some operations don't change the solution set of the original equation, i.e., they will give you an equivalent equation. This includes adding, subtracting, multiplying, and dividing both sides by the same number (but don't divide by zero!). Multiplying both sides by a variable (or an expression that includes a variable) may add an additional solution. For example: x = 5 has only one solution (5). If you multiply both sides by "x", you get: x^2 = 5x (x squared = 5x), which has the additional solution zero. Similarly, dividing both sides of an equation by the same may eliminate a solution (as compared to the original equation); squaring may add solutions, and taking the square root may eliminate solutions. Similarly, applying other functions, such as trigonometric functions and inverse trigonometric functions, may change the solution set - you need to be aware of the behavior of each specific type of function.
To write an equation that includes the keyword "how to write an equation," you can use a variable like x to represent the phrase. For example, the equation could be x "how to write an equation."
A logarithmic equation would be any equation that includes the log function.
A thermochemical equation includes information about the energy changes associated with a chemical reaction, such as enthalpy changes. A balanced chemical equation shows the reactants and products involved in a chemical reaction in their correct proportions. While a balanced chemical equation gives the stoichiometry of the reaction, a thermochemical equation provides additional information about the heat flow during the reaction.

I think this might read "4x+5 = 4x-1". Subtracting 4x from both sides cannot upset the equality, and then you have +5 = -1, which is nonsense. One moral of this is "make sure your equation makes sense, and actually includes an = sign."
