Answer 1

Additional method = A procedure for solving simultaneous equations; linear combination method.

How do you solve using the addition method?

1st: Line up the variables in both equation, x above x, y above y, = above =, constant above constant.

2nd: (Optional) Multiply one or both equations so the coefficients of one variable are opposites.

3rd: Add the equations to eliminate one variable.

4th: Solve.

Answer 2

Answer:

1. The first method of solving systems of linear equations is the addition method, in which the two equations are added together to eliminate one of the variables. ... Adding the equations means that we add the left sides of the two equations together, and we add the right sides together.
