Question 22623: Can someone help me solve for y:
5(4x + 3) <= -1/2y + 5
20x + 15 <= -1/2y + 5
20x + 15 - 5 <= -1/2y
20x + 10 <= -1/2y
I get lost after this.

Question 22622: Can someone help me solve for x?
(2x + 3y) + 3x = -3(y-4x) this is as far as I got
2x + 3y + 3x = -3y + 12x
5x + 3y = -3y + 12x
3y + 3y = 12x - 5x
6y = 7x

Graph the following equalities. Make sure you shade correctly and pay attention to the 'equal' portion. Also, this should be in cartesian coordinate system (ie x-y graph not a line graph)
#26 y > 5
#27 -2y > 10
#28 5+2y < 3y-2
