Solving Linear Systems Graphically Answers

After adding the two equations to eliminate x you are left with .Solve for y:y =

Substituting y = –2 back into the first equation gives: –2x + = –12

Solve for x. What is the solution to the system of equations?( , )

–2x + y = 32x – y = 4Using elimination to solve this system results in the equation .

Consider this system: Which of the following operations would eliminate the x-terms if the two equations were added together afterward?
