Algebra.Com's Answer #26547 by PaulAllen65270(19)![]() ![]() ![]() You can put this solution on YOUR website! To solve inequalities like this one you need to divide it into two equations. \n" ); document.write( "One equation is \n" ); document.write( " t-4>5 \n" ); document.write( "The other equation is \n" ); document.write( "t-4<6 \n" ); document.write( "You then need to solve both of these equations \n" ); document.write( "t-4>5 \n" ); document.write( " +4>+4 add four to both sides which will not change the inequality sign \n" ); document.write( "t > 9 \n" ); document.write( "Then you want to solve the other equation \n" ); document.write( "t-4<6 \n" ); document.write( " +4<+4 again you add four to both sides which will not change the inequality sign \n" ); document.write( "t < 10\r \n" ); document.write( "\n" ); document.write( "Now you put these two equations back together\r \n" ); document.write( "\n" ); document.write( "9 < t < 10\r \n" ); document.write( "\n" ); document.write( "Which is then your complete answer. To plot this number on a number line it would be anything between 9 and 10 \n" ); document.write( " |
