You can put this solution on YOUR website!
11 + x = -3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract 11 from both sides of the equation to isolate x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-11 + 11 + x = -3 - 11\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The positive and negative 11 cancel each other out on the left side and thus isolating x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = -3 - 11\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = -14\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "THE PROOF:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let x = -14 in the original linear equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "11 + x = -3\r
\n" ); document.write( "\n" ); document.write( "11 + (-14) = -3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-3 = -3....It checks!\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We can now confirm that x = -14 is correct.\r
