Algebra.Com's Answer #90002 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! We can write it like this:\r \n" ); document.write( "\n" ); document.write( "| \n" ); document.write( ": \n" ); document.write( "Remove the abs and we have two equations to solve \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( "Multiply equation by 9: \n" ); document.write( "x - 1 < 18 \n" ); document.write( "x < 18 + 1 \n" ); document.write( "x < 19 \n" ); document.write( ": \n" ); document.write( "and this one is neg 2, reverse the inequalitiy sign \n" ); document.write( " \n" ); document.write( "Multiply equation by 9 \n" ); document.write( "x - 1 > -18 \n" ); document.write( "x > -18 + 1 \n" ); document.write( "x > -17 \n" ); document.write( ": \n" ); document.write( "interval notation: (-17, +19) \n" ); document.write( " \n" ); document.write( " |
