What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the number be x.

so,  2 less than 3 times a certain number is the same as 4 more than the product of 5 and 3

3x - 2 = 4+ 5(3)

3x- 2 = 4 + 15

3x- 2= 19

3x= 21

x= 21/3

x= 7

Hence, the number is 7.
