Algebra.Com's Answer #357838 by bucky(2189) ![]() You can put this solution on YOUR website! You can work these problems using the same rules that you have learned for solving equations with this exception: If you multiply or divide both sides of the inequality BY A NEGATIVE Quantity, you must reverse the direction of the inequality sign. \n" ); document.write( ". \n" ); document.write( "So, just imagine for the time being that the > sign in this problem is an equal sign. \n" ); document.write( ". \n" ); document.write( "You are given: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "You are expected to solve this for x. In an ordinary equation you would get rid of the -5 on the left side by adding 5 to both sides. You do the same here. Just add 5 to both sides and the problem becomes: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "And that's the answer to this problem. x is greater than 5. \n" ); document.write( ". \n" ); document.write( "We didn't make use of the exception because we didn't have to multiply or divide both sides by a negative quantity to solve for x. But don't forget that rule. It will be useful for other problems of this type. \n" ); document.write( ". \n" ); document.write( "For the time being just think of working these problems by following the rules you already know for equations. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand inequalities a little better. \n" ); document.write( " |
