Algebra.Com's Answer #28706 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! can you help me to solve for x in terms of y and solve for y in terms of x for the following equation. \n" ); document.write( "3y^2+4xy-9y^2=-1 \n" ); document.write( "Combining like terms you get the following: \n" ); document.write( "4xy-6y^2=-1 \r \n" ); document.write( "\n" ); document.write( "Then x=[6y^2-1]/4y\r \n" ); document.write( "\n" ); document.write( "To solve for \"y\" rearrange and use the quadratic formula to get: \n" ); document.write( "6y^2-4xy-1=0 \n" ); document.write( "y=[4x+sqrt((4x)^2+4(6)]/12=[4x+sqrt(16x^2+24)]/12=[2x+sqrt(x^2+6)]/6 \n" ); document.write( "OR \n" ); document.write( "y=[2x-sqrt(x^2+6)]/6\r \n" ); document.write( "\n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
