Algebra.Com's Answer #795225 by Boreal(15235) You can put this solution on YOUR website! the first and third add to -6c=-18 or c=3 \n" ); document.write( "- \n" ); document.write( "4a-5b=7 and \n" ); document.write( "a+5b+15=-2; change signs to a+5b+5c=-2 \n" ); document.write( "so 5a=-10 and a=-2. That makes -5b=15 so b=-3 \n" ); document.write( "(-2, -3, 3) \n" ); document.write( " |
