The solution is (2, -4). 3. Find the solution to the system of linear equations using substitution. 3x − 2y = -5 5x + 5y = 0 Enter the system’s solution as an ordered pair, including the comma. If the system has no solution, enter “none”. If the system has infinitely many solutions, enter “infinitely many solutions”. Solution: ___ (-1, 1) _______ 4. Find the solution to the system of linear equations using elimination. 4x − 6y = 2 -4x + 3y = −11 Solution: ___ (5, 3) _______ Enter the system’s solution as an ordered pair including the parentheses and comma. If the system has no solution, enter “no solution”. If the system has infinitely many solutions, enter “infinitely many solutions”.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
