5(X-3)/4=x+1
\n" ); document.write( "5x-15=4x+4
\n" ); document.write( "x=19
\n" ); document.write( "----------------
\n" ); document.write( "3(x+12)/5 = x+2
\n" ); document.write( "3x+36=5x+10
\n" ); document.write( "2x=26
\n" ); document.write( "x=13
\n" ); document.write( "-----------
\n" ); document.write( "2/(3n+4)=10-4/3n
\n" ); document.write( "2/(3n+4) = (30n-4)/3n
\n" ); document.write( "Cross-multiply to get:
\n" ); document.write( "6n=(3n+4)(30n-4)
\n" ); document.write( "6n=90n^2+108n-16
\n" ); document.write( "90n^2+102n-16=0
\n" ); document.write( "45n^2+51n-8=0
\n" ); document.write( "Use the quadratic formula to get:
\n" ); document.write( "n=[-51+-sqrt(51^2-4*45*-8)]/90
\n" ); document.write( "n=[-51+-sqrt(4041)]/90
\n" ); document.write( "n=0.139654... or n=-1.27298...
\n" ); document.write( "---------
\n" ); document.write( "c=5over6 and d=1over4,evaluate:8cover-d
\n" ); document.write( "8c/(-d)=8*5/(-1/4)= 40/(-1/4)=-160
