What is the elimination method in linear equations?

In which elimination process You add or subtract those equations to get one equation in a variable. If the coefficients of a variable are opposite, add them up equations to remove a variable and if the coefficients of a variable are equal, subtract the equations to remove a variable.

How do you solve a question by elimination?

steps to solve equations by the elimination method

The first step is to multiply both linear equations by a non-zero constant. This would make the coefficients of each of the variables, x or y, numerically equal.

The next step is to add or subtract one equation from the other in such a way that one of the variables can be easily eliminated.

Why does the elimination method work?

Because it allows us to eliminate or get rid of one of the variables, allowing us to solve a simplified equation. Some textbooks refer to the elimination process Additionally method or the method the linear combination. That’s because we’re going to combine two equations by addition!

Why does Gaussian elimination work?

We know that adding and subtracting equations doesn’t change the solution set, so the first set of equations has the same solution as the second set. So the start Gaussian elimination is valid”. And you keep doing such steps until you get the matrix in echelon form, which is easy to handle.
