Given that z=3y+2/y-1, express y in terms of z
\n" ); document.write( "and hence find the value of y when z=1/2
\n" ); document.write( "------------------
\n" ); document.write( "z=(3y+2)/(y-1)
\n" ); document.write( "zy - z = 3y + 2
\n" ); document.write( "zy-3y = 2+z
\n" ); document.write( "y(z-3) = z + 2
\n" ); document.write( "y = (z+2)(z-3)
\n" ); document.write( "--------------------
\n" ); document.write( "Let z = 1/2
\n" ); document.write( "y = (5/2)/(-5/2)
\n" ); document.write( "y = -1
\n" ); document.write( "================
