Understanding algebra
Algebra is a branch of mathematics that focuses on manipulating symbols and mathematical expressions to understand and solve various problems. Algebra allows you to work with numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) to analyze complex situations.
In algebra, you use letters (variables) to represent unknown or changeable values, so that we can find solutions to various problems.

Group of algebraic formulas.
1. Algebraic formula for linear equations
A linear equation is a mathematical equation in the form ax + b = c, where a, b, and c are constants, and x is the variable we are looking for. Here is the formula:
ax + b = c
Problems example:
Determine the value of x in the following equation: 3x + 5 = 14.
Discussion:
We want to find the value of x. First, subtract 5 from both sides of the equation:
3x + 5 – 5 = 14 – 5
3x = 9
Next, divide both sides by 3:
(3x) / 3 = 9 / 3
x = 3
So, x = 3.
