Algebra.Com's Answer #694493 by kvijioct(5) ![]() You can put this solution on YOUR website! First Condition \n" ); document.write( "x+y=2(x-y) \n" ); document.write( "x+y=2x-2y \n" ); document.write( "x=3y------------Eqn 1.\r \n" ); document.write( "\n" ); document.write( "Second Condition - This condition is not clear in the given question-one number is 5 more than the 2 numbers. I have assumed it to be 'one number is 5 more than the second number' and have solved it below.\r \n" ); document.write( "\n" ); document.write( "x=y+5 \n" ); document.write( "3y=y+5 (Substituting for 'x' from Eqn 1) \n" ); document.write( "2y=5 \n" ); document.write( "y=5/2=2.5\r \n" ); document.write( "\n" ); document.write( "So, x=3y \n" ); document.write( " =3*2.5 \n" ); document.write( " =7.5\r \n" ); document.write( "\n" ); document.write( "So, the solution is x=7.5, y=2.5 \n" ); document.write( " \n" ); document.write( " |
