1. Determine whether the given ordered pair is a solution of the systems of equations? 6x-y =44 3x -6y = 0 Is the ordered pair (8,4) a solution? Yes 2. Solve the system of equations by graphing x + y =3 y – x = 3 The solution set of the system of equations is {0,3 } 3. Solve the system of equations by graphing x – 2y = 8 x + 2y = 0 The solution set is {4,-2} 4. Write the percent as a fraction or mixed number in lowest terms. 62.5% = .625 5. Solve the system of equations by graphing y = 2x -2 6x + y = 6 The solution set of the system of equation is {1,0} 6. Solve the system of equations by substitution. 2x + y = 18 y = 4x The solution set is {3,12} 7. solve by the substitution method 5x + 9y = -1 x = 4-6y The solution set is {-2,1} 8. Solve by the substitution method. 15x – 20y = 1 15y = -1 + 10 x The solution set is {7/5 , 13/15 } 9. Solve the system by the substitution method. 54x – 6y = 18 y = 9x + 3 The solution set to the system is { impossible}

### What students are saying

• 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.
