Introduction To Algebra

Algebra is that branch of mathematics, which includes the study of the expressions containing the variables and the constants. Here we are going to learn about Introduction to Algebra. While talking about Intro to Algebra, we Mean the basic knowledge of the variables and their mathematical Relations with different operators. Algebra Introduction includes the basic study of the use of the operators and how the different values of the variables effect the given equations of algebra.

If we have some equality with the left and the right side of the equation, we say that in order to find the value of the variable, we will use hit and trial method, by which we check the left side of the equation and the right side of the equation are equal or nit. In case we have both the sides of the equations as equal, it indicates that the particular value of the variable satisfies the equation. In case the two sides of the equation are not equal, then we say that the particular value does not satisfy the equation.

Now we look at the following equation, 3x + 5 = 8;
So we say that the variable x is unknown, and then if we need to find the value of the value of the unknown variable in the equation, it means that we go on trying different values of ‘x’ and check by which value, the left side of the equation is equal to the right side of the equation. So we start with x = 0
3 * 0 + 5 = 0 + 5 = 5,
 So this time it is not equal to the right side of the equation. Thus x = 0 is not the solution. Now we try for x = 1, so 3 * 1 + 5 = 3 + 5 = 8.
So LHS = RHS, so x= 1 is the solution.
