Algebra.Com's Answer #560779 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! The obvious substitution to make is for y as defined with the second equation. Substitute the expression into the quadratic, first equation; simplify and solve for x.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Another way to view the system is that you have two equal expressions for y.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "Solve that and continue. \n" ); document.write( " |
