To avoid confusion, remove the parentheses first, working the problem on the inside of the brackets first.\r
\n" ); document.write( "\n" ); document.write( "-[2z - (5z+2)] = 2 + (2z +7)
\n" ); document.write( "-[2z - 5z - 2] = 2 + 2z + 7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Combine like terms:
\n" ); document.write( "-[-3z - 2] = 9 + 2z\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now remove the brackets, the same as parentheses:
\n" ); document.write( "3z + 2 = 9 + 2z\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Get the variables all on the left side by subtracting 2z from each side:
\n" ); document.write( "3z - 2z + 2 = 9 + 2z - 2z
\n" ); document.write( "z + 2 = 9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract 2 from each side:
\n" ); document.write( "z + 2 - 2 = 9 - 2
\n" ); document.write( "z = 7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "R^2 at SCC
\n" ); document.write( "
\n" );
