## kimberly_18ann 2 years ago how about if it is fraction? wat will I do 1st? 3x/4 ≥-6 Thank you!

1. RolyPoly

1. Multiply both sides by 4 2. Divide both sides by 3

2. RolyPoly

Or 1. Multiply both sides by 4/3

3. kimberly_18ann

ok, thank you

4. kimberly_18ann

i can't remember if it is negative when you subtract a lower positive number from a higher negative number? Help pls. Thank you!

5. RolyPoly

2-3 = -1

6. RolyPoly

Does it help?

7. kimberly_18ann

yes. a big heLp.... now I don't have hesitation in my answer! Thanks

8. kimberly_18ann

wat if negative divide by negative? is it equal to positive?

9. RolyPoly

Yes.

10. RolyPoly

+ve times +ve = +ve +ve times -ve = -ve -ve times -ve = +ve Same holds for division.

11. kimberly_18ann

ahm...okay, I thought It was different rule!

12. kimberly_18ann

I got 2 unfinished answers w/ my questions, bcoz now I'm confused which answer will i proceed, which is correct 3x/4 times 4/3 is equal to 12x/7 or 9x*16?

13. RolyPoly

$\frac{3x}{4} ≥-6$$\frac{4}{3}\times\frac{3x}{4} ≥-6\times \frac{4}{3}$Simplify the left and right side.

14. kimberly_18ann

I have 2 different answers bcoz I can't remember if it's correct to cross multiply it!

15. RolyPoly

$\frac{4}{3}\times\frac{3x}{4} ≥-6\times \frac{4}{3}$$\frac{4\times3x}{3\times 4} ≥\frac{-6\times 4}{3}$

16. RolyPoly

If you don't understand / can't handle this, just use the first method I told you: 1. Multiply both sides by 4 2. Divide both sides by 3

17. kimberly_18ann

I've got x≥-8 is my answer correct?

18. HELP!!!!

-1

19. RolyPoly

-8 is right...

20. RolyPoly

I mean x≥-8
