15x-2=21x+10\r
\n" ); document.write( "\n" ); document.write( "Since 21x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 21x from both sides.
\n" ); document.write( "15x-2-21x=10\r
\n" ); document.write( "\n" ); document.write( "Since 15x and -21x are like terms, add -21x to 15x to get -6x.
\n" ); document.write( "-6x-2=10\r
\n" ); document.write( "\n" ); document.write( "Since -2 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 2 to both sides.
\n" ); document.write( "-6x=2+10\r
\n" ); document.write( "\n" ); document.write( "Add 10 to 2 to get 12.
\n" ); document.write( "-6x=12\r
\n" ); document.write( "\n" ); document.write( "Divide each term in the equation by -6.
\n" ); document.write( "-(6x)/(-6)=(12)/(-6)\r
\n" ); document.write( "\n" ); document.write( "Simplify the left-hand side of the equation by canceling the common factors.
\n" ); document.write( "x=(12)/(-6)\r
\n" ); document.write( "\n" ); document.write( "Simplify the right-hand side of the equation by simplifying each term.
\n" ); document.write( "x=-2 \n" ); document.write( "

\n" );
