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( "================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
