So we get aMoreWith two variables just X's and Y's. So let's multiply this equation by negative 7. So we get a positive 7y. We can add it to this equation. And eliminate the Y's.

Combination involves adding the two equations together to eliminate a variable. Often, one or both of the equations must be multiplied by a constant before they are added together.

So that should really just zero equals xMoreSo when I do that I get 2y plus negative 2y that's 0 Y. So that should really just zero equals x plus negative 4x. So I'm doing imaginary one plus a negative 4. So that's gonna be negative 3x.

Two or more linear equations that all contain the same unknown variables are called a system of simultaneous linear equations. Solving such a system means finding values for the unknown variables which satisfy all the equations at the same time.

If you have two different equations with the same two unknowns in each, you can solve for both unknowns. There are three common methods for solving: addition/subtraction, substitution, and graphing. Addition/subtraction method.
