The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol. See: Variable.

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

So if you multiply both sides by 3 you'll get negative 6 negative 2 X and when you divide both sidesMoreSo if you multiply both sides by 3 you'll get negative 6 negative 2 X and when you divide both sides by negative 2 of course you end up with 3 for the value of x.
