## anonymous 4 years ago 9x-(7x+1/2)=3x+(1/2-X)

1. anonymous

x=0

2. anonymous

do you know how to do the distributive property?

3. anonymous

Yea bt im nt sure hw to strt

4. anonymous

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. anonymous

the answer is "all real numbers"

6. anonymous

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

7. anonymous

the answer is x=x not just all real numbers

8. anonymous

Thanks can u help with thid

9. anonymous

-4/7x=-12+4

10. anonymous

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

11. anonymous

7x sorry

12. anonymous

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

13. anonymous

7 cancels out?

14. anonymous

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

15. anonymous

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. anonymous

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

17. anonymous

7

18. anonymous

i got x = 14

19. anonymous

Hw/

20. anonymous

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

21. anonymous

@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. anonymous

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

23. anonymous

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. anonymous

Hw would i work it out?

25. anonymous

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

26. anonymous

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