Question

what is algebra can i have an example?

Answer 1

It is a part of mathematics in which letters and other general  symbols are used to represent numbers and quantities in formulas and equations.
example : 2x -  3y = 10z

Answer 2

Algebra uses letters (like x or y) or other symbols in place of unknown values.

For example: x + 3 = 7
 here , "x" is unknown (often called the "variable").
so, x = 7-3
=4.
thus the value of x is 4.
got it?
