Algebra.Com's Answer #203928 by richwmiller(17219) You can put this solution on YOUR website! You don't seem to know how to add nor multiply. \n" ); document.write( "-7x>1/15 \n" ); document.write( "add 7x to both sides \n" ); document.write( "0>1/15+7x \n" ); document.write( "but that will get us nowhere \n" ); document.write( "how did you go from > to =? \n" ); document.write( "and why didn't you multiply the 7 by 15/1 ?\r \n" ); document.write( "\n" ); document.write( "So anyways to solve the inequality\r \n" ); document.write( "\n" ); document.write( "multiply by -1/7 and change signs \n" ); document.write( "-7*-1/7<1/15*-1/7 \n" ); document.write( "x<-1/105 \n" ); document.write( " |
