## hiralpatel121 3 years ago I need help with the attached problem please.

1. hiralpatel121

2. hartnn

first use the distributive property twice $a(b+c)=ab+ac$ tell me what u get?

3. hartnn

*thrice

4. dpaInc

9x + 5(2x + 11) = 3(x + 21) + 2(8x - 3) yep... use distributive property first.... then combine like terms...

5. hiralpatel121

9x+10x+55 = 3x+63 + 16x-6

6. dpaInc

CLT.. combine like terms, then solve for x now....

7. hartnn

correct,now combine like terms 9x,10x,3x,16x 55,63,-6

8. hiralpatel121

Then you get: 19x+55 = 19x+57

9. hiralpatel121

Would this be a no solution? Since 19x-19x = 0?

10. hartnn

thats correct,so now that 19x gets cancelled and there will be no solution

11. dpaInc

nice work...

12. hiralpatel121

So the answer is "No Solution" ?

13. hartnn

yup :)

14. hiralpatel121

Okayy. I need help with 2 more problems.

15. hartnn

16. hiralpatel121

17. hartnn

what u got?

18. hiralpatel121

I don't know how to solve this..

19. hartnn

1.divide by W 2.subtract 2 3.divide by z all these to both sides

20. hiralpatel121

You don't distribute W first?

21. hartnn

that would complicate it,though possible.

22. hiralpatel121

This is what I got: G = W (2+zp) G/W = W(2+zp)/W G/W – 2 = zp G/W/z – 2 = p

23. hartnn

ok,in last step,u missed dividing z to 2 also G/W/z=G/Wz

24. hiralpatel121

So it would be: G/Wz - 2/z = p ?

25. hartnn

yup,which u can write as $\frac{G-2W}{Wz}$
