System of linear equations in 2 variables
WebWe now wish to add the two equations but it will not result in either x or y being eliminated. Therefore we must multiply the second equation by 2 on both sides and get: $$2x-2y=8$$ $$2x+2y=2$$ Now we attempt to add our system of equations. We commence with the x-terms on the left, and the y-terms thereafter and finally with the numbers on the ... WebAug 13, 2024 · An example of a system of two linear equations is shown below. We use a brace to show the two equations are grouped together to form a system of equations. { 2 …
