9) |10x – 5| > -1510) |10x – 5 | < -15
3) Systems algebraically:(MUST BE CHECKED IN BOTH!)
1) 5x - 2y= -40 2) -6x + 2y = -56
7x + 2y = -8 7x – 3y = 58
3) x = 2y -8 4) 5x – 6y = 52
5x – 3y = -12 7x + 5y = -88
5) 4x + 5 = y 6) 7x + 6y = 21
8x - 5y = 23 5x + 2y = -1
7) 5x – 7y = 137 8) x = 5 – 2y
3x + 11y = -85 6x – 5y = 81
9) 6x + 5y = -8 10) y = 4x - 27
11x + 4y = 37 8x – 5y = 75
