Algebra.Com's Answer #122667 by Personal Trainer DC(4)![]() ![]() ![]() You can put this solution on YOUR website! Since it's an absolute value, you need to re-write the inequality considering the negative and positive side:\r \n" ); document.write( "\n" ); document.write( "-2 < 2y + 6/3 - 9 < 2\r \n" ); document.write( "\n" ); document.write( "Then, add 9 to both sides:\r \n" ); document.write( "\n" ); document.write( "7 < 2y + 6/3 < 11\r \n" ); document.write( "\n" ); document.write( "Then, subtract 6/3 (ie. 2) from both sides:\r \n" ); document.write( "\n" ); document.write( "5 < 2y < 9\r \n" ); document.write( "\n" ); document.write( "Then, divide by 2:\r \n" ); document.write( "\n" ); document.write( "5/2 < y < 9/2\r \n" ); document.write( "\n" ); document.write( "In interval notation, (5/2, 9/2) \n" ); document.write( " |
