Solve for x: 2(2x - 3) - 5(x + 1) = 2x - 7\r
\n" ); document.write( "\n" ); document.write( "2(2x - 3) - 5(x + 1) = 2x - 7
\n" ); document.write( "4x - 6 - 5x - 5 = 2x - 7
\n" ); document.write( "4x - 5x - 2x = 6 + 5 - 7
\n" ); document.write( "-x - 2x = 11 - 7
\n" ); document.write( "-3x = 4
\n" ); document.write( "x = -4/3\r
\n" ); document.write( "\n" ); document.write( "I see this in your attempt: \"4x - 5x -2x = 3x\" that should be -3x not 3x.
\n" ); document.write( "Also in \"- 6 - 5 -7 = - 18\" that should be -6 - 5 + 7 or -11 + 7 = -4.
\n" ); document.write( "So -3x - 4 = 0 --> -3x = 4 --> x=-4/3.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
