math/learn/algebraic equations/
An algebraic equation is a number problem that contains an equals sign and at least one variable.
In this equation, your objective is to find the number that x stands for. The x is called a variable. You may use any of the letters of the alphabet as a variable, but x, y and z are the most commonly used letters. To solve an equation, you find the number that the variable represents.
Here is an example: 4+z=14. z = 10. Sound familiar? You might remember in Grade 1 when you had to fill in grey boxes with a number to make numerical sentences true. Now instead of a grey box, we use a variable.
