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
