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

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

    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?

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