Question 747980: 4w-6>6w-20
Answer by lenny460(1073)   (Show Source):
You can put this solution on YOUR website! 4w - 6 > 6w - 20
Add 6 to each side of the inequality.
4w - 6 + 6 > 6w - 20 + 6
Combine like terms:
-6 + 6 = 0
-20 + 6 = -14
We now have:
4w > 6w - 14
Subtract 6w from each side of the inequality.
4w - 6w > 6w - 14 - 6w
Combine like terms:
4w - 6w = -2w
6w - 6w = 0
Therefore:
-2w > -14
Divide each side by -2
w < 7
Answer:
w < 7
Please Note: When you divide inequalities by a negative number you flip (change) the inequality sign.
