they work just like equations , except there is an inequality sign
... if you multiply or divide by a negative quantity , the arrow is reversed
I need help a little bit on my math.
1. 6> - 2/3(7x-2)
2. -1/3(x - 9) + 4 < - 2
3. -1/4 x - 8 < 3/4

1. 6 > - 2/3(7x-2)
6 > -14x/3+4/3
Multiply both sides by 3:
18 > -14x + 4
14 > -14x
Divide both sides by -14 and reverse inequality sign.
-1 < X.
Prob. #2 and #3 are similar to #1.
6 > -14x/3+4/3
Multiply both sides by 3:
18 > -14x + 4
14 > -14x
Divide both sides by -14 and reverse inequality sign.
-1 < X.
Prob. #2 and #3 are similar to #1.
