You can put this solution on YOUR website!
|x-3|>|2x+1|
\n" ); document.write( "---------------
\n" ); document.write( "if x = 0, you get |-3|>|1|, which is true: so x=0 is part of the solution.
\n" ); document.write( "--------------
\n" ); document.write( "If both x-3 and 2x+1 are positive you get:
\n" ); document.write( "x-3 > 2x+1
\n" ); document.write( "x<-4
\n" ); document.write( "Testing x=-10 you get:
\n" ); document.write( "|-13| > |-19| which is false.
\n" ); document.write( "---------------------
\n" ); document.write( "If both x-3 and 2x+1 are negative you get:
\n" ); document.write( "-x+3 > -2x-1
\n" ); document.write( "x > -4
\n" ); document.write( "Testing x=0 you know already this is true so x>-4 is part of the solution.
\n" ); document.write( "--------------------
\n" ); document.write( "If x-3 is positive and 2x+1 is negative you get:
\n" ); document.write( "x-3 > -2x-1
\n" ); document.write( "3x > 2
\n" ); document.write( "x>2/3
\n" ); document.write( "Testing x=1 you get:
\n" ); document.write( "|1-3| > |2+1| which is false
\n" ); document.write( "---------------------------------
\n" ); document.write( "If x-3 is negative and 2x+1 is positive you get:
\n" ); document.write( "-x+3 > 2x+1
\n" ); document.write( "3x<2
\n" ); document.write( "x <2/3
\n" ); document.write( "Testing 0 you know already this is true so x < 2/3
\n" ); document.write( "-----------------------
\n" ); document.write( "Putting that all together you get -4 < x < 2/3
\n" ); document.write( "==================
\n" ); document.write( "PS: Graphing it is easier.
\n" ); document.write( "==================
