In elementary algebra, those symbols (today written as Latin and Greek letters) represent quantities without fixed values, known as variables. Just as sentences describe relationships between specific words, in algebra, equations describe relationships between variables. Example: x+y=3, where x=2. find a value of y. Here, x=2, So, 2+y=3 or, y=3-2 or, y=1
