Question 57435: 2 - 4x + 7x + 8 < 6x - 5x

2-4x+7x+8<6x-5x
2+8-4x+7x<6x-5x
10+3x 10+3x-3x 10<-2x When you multiply or divide by a negative number you have to flip the inequality sign.
10/-2>-2x/-2
-5>x
:
Write it with the variable on the left, it makes graphing and interval notation easier to do. Make sure the inequality symbol is still opening towards the same number.
x>-5
That might be all you need, you didn't specify.
Interval notation (-5,infinity)
