An equation is a mathematical statement that asserts the equality of two expressions. Equations consist of the expressions that have to be equal on opposite sides of an equal sign. Energy equation is an equation about energy.

That is called an equation. An equation has an equal sign (=), and expressions on both sides of the equal sign.

If both sides are equal, it's called an equation. If both sides are NOT equal, it's called an inequality.

To check if an equation is balanced, you should check if the number of atoms on both sides are equal or not. If they are not equal, balance them suitably. Next, check the charges on both sides. If charges are unequal, balance them too.

The equation for the Pythagoras Theorem is written as: a2 + b2 = c2. The theory of this equation is to provide analysis of the sum of squares from 2 different sides.

By determining whether the numbers of each kind of atoms in the equation are the same on both sides of the equation.

check the solution.

Substitute the value found back into the equation, evaluate the expressions and see if the resulting equation is true.

An equation has two sides, and each of these sides is equal to the other.

That's an extraneous solution. You need to check for these when algebraically solving equations, especially when you take both sides of an equation to a power.

An expression is any combination of symbols that can be evaluated to a number (or perhaps to some other data type). An equation has an equal sign, and an expression on both sides of the equal sign - it is a claim that the two expressions are equal.
