Question 64969: Solve the system of inequalities by graphing.
y>x
2x+y
2. graph:5x+3y greater than or equal to 15
x is less than or equal to y
x is less than or equal to 4

3. find the max. and min. values and where they occur for z=4x+7y subject to the constraints:
x+y is greater than or equal to 2
3x-4y is less than or equal to 6
6y is less than or equal to x+12
