2. Warm-Up Questions
1. Solve: 4(2x-6) - 7(3x+8) = 89
2. Solve for x: -9x < 18
3. 3/17x < -1
4. -3| x + 4| - 2 = 4 + 5| x + 4|

3. Multi-Step & Compound
Inequalities
1. 3x -2(6x - 4) > 4 - (4x + 6)
1. 3x -12x + 8 > -2 - 4x; -5x > -10; x<2
2. 6x - 4 < 2x + 12
2. 4x < 16 x<4
3. 3x - 15 > 4 + 5x

4. Multi-Step & Compound
Inequalities
If a compound inequality uses 'and', both inequalities
and
must be true. The solution set is the intersection of the
two inequalities.
1. Graph the solutions set of x < 2 and x > -1
The solution set is therefore: { x| -1 < x < 2}
