7x+4=3x-20
\n" ); document.write( "Subtract 3x to the left.
\n" ); document.write( "4x+4=-20
\n" ); document.write( "Subtract 4 to the right.
\n" ); document.write( "4x=-24
\n" ); document.write( "Divide -24/4 to isolate variable \"x\".
\n" ); document.write( "x=-6\r
\n" ); document.write( "\n" ); document.write( "Plug it back it to prove the solution.
\n" ); document.write( "7(-6)+4=3(-6)-20
\n" ); document.write( "-38=-38
