the solution procedure of linear equation is:

Suppose that M, N, and P are expressions that may or may not include variables, and then the following constitute some rules that will be helpful in the solution of linear equations

Rule 1: Additional rule

            If M = N then M + P = N + P

Rule 2: Subtraction rule

            If M = N, Then M - P = N - P

Rule 3: multiplication rule

            If M = N and P ≠ O then M x P = N x P

Rule 4: Division rule

            If P x M = N and P ≠ O

            And N/P = Q    Q being a material number then

            M = N/P
