I missed one of my lectures and have nobody else to ask for help. I have a homework assignment due at the beginning of my next class along with a exam right at the beginning of class. I am stuck on 3 different problems. I'm not asking for somebody to do them for me, but I am asking for an explanation on how to solve them. Feel free to change the problem up so you don't feel like you're just helping me with my homework. Here are the 3 problems I have.

1. Solve the absolute value equation.

|5x+3|=|2x-7|

2. Graph (Shade on true side)

3x-2y >= 6

3. Graph the solution to the system of linear inequalities. (Shade on true side)

2x+3y =< 6

3x-2y =< 6
