Question

Explanation of the elimination method of linear equation in 2 variable​

Answer 1

The elimination method of solving systems of equations is also called the addition method.

To solve a system of equations by elimination we transform the system such that one variable “cancels out”.

In order to solve for y, take the value for x and substitute it back into either one of the original equations.

In the elimination method, you either add or subtract the equations to get an equation in one variable.

Answer 2

Explanation:

coefficients of one variable are opposites you add the equations to eliminate a variable

• when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

• We can eliminate the x-variable by addition of the two equations. The solution of the linear system is (0, 2).
