Question 56437: I think I get scared of fractions and algebra. I am not sure I ask previously in the correct way. Can you help with this? Thanks!
solve for x:
13 4
_______ = _______
x-1 x+2
or 13 over x-1 equal(=) to 4 over x +2. Maybe that is clear enough.

any assitance would be appreciated.''.

You can put this solution on YOUR website!
13/(X-1)=4/(X+2)
CROSS MULTIPLYING WE GET
4(X-1)=13(X+2)
4X-4=13X+26
4X-13X=26+4
-9X=30
X=30/-9
X=-10/3
PROOF
13[(-10/3)-1]=4/[(-10/3)+2]
13[(-10/3)+2]=4[(-10/3)-1]
-130/3+26=-40/3-4
-130/3+78/3=-40/3-12/3
-52/3=-52/3
