Algebra.Com's Answer #177799 by unlockmath(1688)![]() ![]() You can put this solution on YOUR website! Hello, \n" ); document.write( "To solve this, let's multiply the first equation by -2. \n" ); document.write( "(-2)4x+(-2)2y=(-2)4 that gives us: \n" ); document.write( "-8x-4y=-8 Now we can add this to the second equation. \n" ); document.write( "8x+4y=0 Notice the y and x cancels out leaving us with: \n" ); document.write( "0=-8 This obviously doesn't make sense so there is NO SOLUTION to this problem. \n" ); document.write( "Check out my book at www.math-unlock.com \n" ); document.write( "RJ Toftness \n" ); document.write( " \n" ); document.write( " |
