Algebra.Com's Answer #23598 by junior403(76) ![]() You can put this solution on YOUR website! y = -x + 2 \n" ); document.write( "y = -x - 5 \n" ); document.write( "First lets put this in standard form by moving the x to the left side of the equation as a positive... \n" ); document.write( "x + y = 2 \n" ); document.write( "x + y = -5 \n" ); document.write( "Already we can see how this may turn out, but lets continue on... \n" ); document.write( "Multiply the first set by a -1 in order to set up the elimination process. \n" ); document.write( "-1(x + y = 2) \n" ); document.write( "Now distribute... \n" ); document.write( "-x - y = -2 \n" ); document.write( "x + y = -5 \n" ); document.write( "Now perform the indicated operations... \n" ); document.write( "-x + x = 0 \n" ); document.write( "-y + y = 0 \n" ); document.write( "-2 -5 = -7 \n" ); document.write( "so this reads... \n" ); document.write( "0 + 0 = -7 \n" ); document.write( "or \n" ); document.write( "0 = -7 \n" ); document.write( "This is not possible so... \n" ); document.write( "There is no solution to this system. The answer is C. \n" ); document.write( "I hope this helps... \n" ); document.write( "Good Luck! \n" ); document.write( " |
