A third method of solving systems of linear equations is the addition method. In this method, we add two terms with the same variable, but opposite coefficients, so that the sum is zero. Of course, not all systems are set up with the two terms of one variable having opposite coefficients.
How do you do addition method?
- Put two given equations on top of each other and label them. …
- Select the variable that needs to be removed. …
- Select the equation to convert the coefficient of the variable. …
- Change the coefficient of the equation. …
- Add the two equations and substitute the result into the original equation.
What is the addition or subtraction method?
In the addition/subtraction method, the two equations in the system are added or subtracted to create a new equation with only one variable. … Add the equations to produce a single equation with one variable. Solve for the variable. Substitute the variable back into one of the equations and solve for the other variable.
