## julie001 3 years ago 9x-(7x+1/2)=3x+(1/2-X)

1. vipul92

x=0

2. gaara438125

do you know how to do the distributive property?

3. julie001

Yea bt im nt sure hw to strt

4. lharrell97

9x-(7x+1/2)=3x+(1/2-X) 9x-7x=2x 2x+1/2=3x+1/2-x 2x+1/2=2x+1/2 2x=2x x=x

5. lharrell97

the answer is "all real numbers"

6. gaara438125

$9x -1(7x+\frac{ 1 }{ 2 }) = 3x + 1(\frac{ 1 }{ 2 }-x)$ does that look nicer? :}

7. gaara438125

the answer is x=x not just all real numbers

8. julie001

Thanks can u help with thid

9. julie001

-4/7x=-12+4

10. gaara438125

well to get rid of the fraction multiply both sides by 7 to get what

11. gaara438125

7x sorry

12. gaara438125

or divide each side by four leaving the left side negative seven

13. julie001

7 cancels out?

14. gaara438125

$\frac{ -4 }{ 7x } = -12 + 4$

15. lharrell97

9x-(7x+1/2)=3x+(1/2-X) lets say x=34 306-238+1/2=102+1/2-34 68+1/2=68+1/2 - lets say that x=113 1017-791+1/2)=339+1/2-113 226+1/2=226+1/2 i can do this all day, because X= ALL REAL NUMBERS

16. gaara438125

on the left do you want to get rid of the seven or the four

17. julie001

7

18. gaara438125

i got x = 14

19. julie001

Hw/

20. gaara438125

multiply both sides by 7x to get $-4 = -84x + 28x$ $-4 = -56x$ $0 = \frac{ -56x }{ -4 }$ 0 = 14x 0 = x

21. gaara438125

@lharrell97 if x=x then it can be anything because you don't know the value of x so it could be an imaginary number or it could be elephant...not JUST all real numbers

22. julie001

Thanks bt i hve more x+5 over 3 = x-3 over 4

23. lharrell97

because you dont know the value of X, it could be any possible number. x could equal 3 billion or it could equal 2. the answer therefore is X= all real numbers... although i can see where you're coming from haha

24. julie001

Hw would i work it out?

25. gaara438125

i think it's probable that X=elephant probably...yeah probably lol

26. gaara438125

look like that? $\frac{ x + 5 }{ 3 } =\frac{ x - 3 }{ 4 }$
