$\"3%28x-2%29%2B7=5%2B4x+\"$
\n" ); document.write( "Distribute the $\"3\"$ .
\n" ); document.write( " $\"3x-6%2B7=5%2B4x\"$
\n" ); document.write( "Combine like terms on the left hand side.
\n" ); document.write( " $\"3x%2B1=5%2B4x\"$
\n" ); document.write( "To get rid of the $\"1\"$ on the left side, subtract $\"1\"$ from both sides.
\n" ); document.write( " $\"3x%2B1-1=5%2B4x-1\"$
\n" ); document.write( " $\"3x%2B0=4x%2B4\"$
\n" ); document.write( " $\"3x=4x%2B4\"$
\n" ); document.write( "To get rid of the $\"4x\"$ from the right side, subtract $\"4x\"$ from both sides.
\n" ); document.write( " $\"3x-4x=4x-4x%2B4\"$
\n" ); document.write( " $\"-x=0%2B4\"$
\n" ); document.write( " $\"-x=4\"$
\n" ); document.write( "Multiply both sides by (-1)
\n" ); document.write( " $\"-%28-x%29=-4\"$
\n" ); document.write( " $\"highlight%28+x=-4+%29\"$
\n" ); document.write( "Verify the solution using the original equation.
\n" ); document.write( " $\"3%28x-2%29%2B7=5%2B4x+\"$
\n" ); document.write( " $\"3%28-4-2%29%2B7=5%2B4%28-4%29+\"$

\n" ); document.write( " $\"-18%2B7=-11\"$
\n" ); document.write( " $\"-11=-11\"$
\n" ); document.write( "True statement, good solution. \n" ); document.write( "
