Linear inequality, 2x+6 < 5(x-3)
- Mathematics - Ravin, Thursday, January 31, 2013 at 5:22pm
2x+6 < 5(x-3) distribute 5 into x-3
2x+6 < 5x-15 move all x to one side
6 < 5x-15-2x simplify
6 < 3x-15 move 15 to other side
6+15 < 3x simplify
21 < 3x get x alone by dividing 3 on both sides
21/3 < 3x/3 simplify
7 < x and thats how you solve it.

2x + 6 < 5x -15
Add 15 and subtract 2x from both sides.
21 < 3x
Divide both sides by 3.
7 < x
