Algebra.Com's Answer #51944 by psbhowmick(878)![]() ![]() You can put this solution on YOUR website! x + 5y = 10 ________(1) \n" ); document.write( "-2x - 10y = -20 ________(2)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Multiply both sides of equation (1) by 2. \n" ); document.write( "Then you get \n" ); document.write( "-2(x + 5y) = -2(10) \n" ); document.write( "-2x - 10y = -20\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "This is same as equation (2). \n" ); document.write( "Thus equations (1) and (2) are identical so there are infinite solutions of 'x' and 'y'. \n" ); document.write( " |
