You can put this solution on YOUR website!
We can write it like this:\r
\n" ); document.write( "\n" ); document.write( "|\"%28x-1%29%2F9\"| < 2
\n" ); document.write( ":
\n" ); document.write( "Remove the abs and we have two equations to solve
\n" ); document.write( ":
\n" ); document.write( "\"%28x-1%29%2F9\" < 2
\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( "\"%28x-1%29%2F9\" > -2
\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( "
\n" );
