Begin with \"7%28x-3%29%3E5x-14\".\r
\n" ); document.write( "\n" ); document.write( "To solve, you can start with the equivalent equation:\r
\n" ); document.write( "\n" ); document.write( "\"7%28x-3%29=5x-14\"\r
\n" ); document.write( "\n" ); document.write( "Multiplying to remove the parentheses:\r
\n" ); document.write( "\n" ); document.write( "\"7x-21=5x-14\"\r
\n" ); document.write( "\n" ); document.write( "Subtracting 5x from both sides:\r
\n" ); document.write( "\n" ); document.write( "\"2x-21%3E-14\"\r
\n" ); document.write( "\n" ); document.write( "Adding 21 to both sides:\r
\n" ); document.write( "\n" ); document.write( "\"2x=7\", so\r
\n" ); document.write( "\n" ); document.write( "\"x=7%2F2\", which may be stated as \"x=3.5\" if you wanted.\r
\n" ); document.write( "\n" ); document.write( "Now we return to the original inequality, and see that our answer is \"x%3E7%2F2\".\r
\n" ); document.write( "\n" ); document.write( "Returning to the original equation, we can check a few values.\r
\n" ); document.write( "\n" ); document.write( "Check \"7%28x-3%29%3E5x-14\", where x = 3. This results in the assertion 0 > 1, which is false. So the value x = 3 does not work, as we expect.\r
\n" ); document.write( "\n" ); document.write( "Check \"7%28x-3%29%3E5x-14\", where x = 4. This results in the assertion 7 > 6, which is true, as we expected given we think the solution is x > 7/2.\r
\n" ); document.write( "\n" ); document.write( "Check \"7%28x-3%29%3E5x-14\", where x = 2. This results in the assertion -7 > -4, which is false. So the value x = 2 does not work, as we expect.\r
\n" ); document.write( "\n" ); document.write( "Check \"7%28x-3%29%3E5x-14\", where x = 5. This results in the assertion 14 > 9, which is true. So the value x = 5 works, as we expect.\r
