Can someone walk me through these? I keep getting the wrong answers to these kind of questions. And when I come up with the right answer, my work is wrong.
1. Show all work to solve this system by the substitution method:
4x+2y=6
6x=9-3y
a. What is the solution? Show all work.
b. Is this system consistent or inconsistent? Explain why.
c. Is this system dependent or independent? Explain why.
2. Given the system 3x = 2y + 7
4x - 3y = 10
a. Solve this system using the Elimination/Addition Method: Put the equations in standard form. What variable did you eliminate first? Show all work!
b. What is the solution?
3. There are three possibilities for the solution set of a system of linear equations. Describe each possibility, including if the system is consistent or inconsistent and if the system is dependent or independent and why. Explain what the graph of the equations for each possibility would look like.
