Week 7 : DQ1 Due Day 1 Please keep in mind this exercise may NOT have a pretty answer. Just simplify if you can, otherwise leave it as a fraction (rather than convert to a decimal) Directions/Steps Here is an example to accompany you. TYPE YOUR ANSWERS in this column 1. Open your reading to section 8.2 page 561. Pick a system of equations from the even numbers on the page. Write the system of equations you chose in this row in the “Type your answers in this column” cell. 2x - y = 6 5x – 2y = 4 9x-2y=3 3x-6=y 2. Is one of the equations solved for a variable already? (Yes or no) With this example of a system: 2x - y = 6 and 5x – 2y = 4 the answer is NO. Neither equation is already solved for a variable. NOTE : If your answer is YES, move on to step #6. Yes, the second equation has already been solved for y. 3. You can pick either equation to solve for either variable, but sometimes one variable or one equation will make more sense.

### 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.
