## anonymous 5 years ago 5(x-1) over 4 equals 3(x+1) over 2. is x=2?

1. anonymous

1/4 does *not* equal 9/2

2. anonymous

you mean 5/4 doesnt equal 9/2

3. anonymous

$\frac{5(x-1)}{4}=\frac{3(x+1)}{2}$so,$5(x-1)=6(x+1)$and,$5x-5=6x+1$giving,$x=-6$

ooops 5x-5=6x+6 x=-11

how do we get 6 for the right side? do i just add up so the Lcd are the same

7. Mertsj

Just look at what I did in the box immediately above. It is the simplest way.

you just cross multiply?

9. Mertsj

Yes

10. anonymous

so when you cross multiply the outside number that outside number for instance 10 on the left side would times the one and make that side bexome 10x-10?

11. Mertsj

2[5(x-1)]=2[5x-5]=10x-10

12. anonymous

why do you subtract 22=2?

13. anonymous

how do you get
