Algebra.Com's Answer #14617 by elima(1433)![]() ![]() ![]() You can put this solution on YOUR website! Hi, I hope I can help! \n" ); document.write( "3x>7x+20 \n" ); document.write( "First of all you need to get the x on one side, so you subtract 7x form both sides; \n" ); document.write( "3x-7x>7x+20-7x \n" ); document.write( "-4x>20 \n" ); document.write( "Now divide each side by -4, remember whenever you divide or multiply a negative number you change direction of sign; \n" ); document.write( " \n" ); document.write( "x<-5 \n" ); document.write( "Now to graph this you will draw a circle around -5 and a solid line to the left covering -6,-7,-8,etc. It's becuase, all those numbers satisfy the equation not including the -5. \n" ); document.write( "Hope you understand \n" ); document.write( "=) \n" ); document.write( " |
