elimination method

Solving simultaneous equation by elimination method is otherwise called as addition method to solve any given simultaneous equations.

In this method, we eliminate one of the unknowns.

Step 1 :- Multiply the given equations by suitable numbers so as to make the coefficients of one of the unknowns, numerically equal

Step 2 :- Add the new equations, if the numerically equal coefficients are opposite in sign, otherwise, subtract them.

Step 3 :- The resulting equation is linear in one unknown. Solve it to obtain the value of one of the unknowns.

Step 4 :- Substitute the value of this unknown in any of the given equations. Solve it to vet the value of the other unknown.

An equation that has only one variable degree is 1 called a simple equation. A linear equation in one variable is the form of Ax + B=0. And A linear equation (linear equation calculator)involves two variables is the form of Ax +By +c =0. Here x and y are variables and A, B, C are constants. When two variables in two linear equations are satisfied by the same pair of values of the variables, the equations are called simultaneous linear equations.
