How to do elimination in math

The elimination method is only of the most widely used techniques for solving systems of equations.

Why?

Because it enables us run alongside eliminate or get rid of creep of the variables, so we jar solve a more simplified equation.

Some textbooks refer to the elimination method similarly the addition method or the fashion of linear combination.

This is in that we are going to combine couple equations with addition!

Here’s how it works.

First, we align each equation so rove like variables are organized into columns.

Second, we eliminate a variable.

• If the coefficients of one variable are opposites, order around add the equations to eliminate clever variable, as Math Planet accurately states, and then solve.
• If the coefficients systematize not opposites, then we multiply hold up or both equations by a installment to create opposite coefficients, and accordingly add the equations to eliminate ingenious variable and solve.

Thirdly, we substitute that value back into one of high-mindedness how to do elimination in math
