Read carefully and set up an equation.
\n" ); document.write( "sum of 6 and twice a number= 6+2x
\n" ); document.write( "7 less than a number = x-7\r
\n" ); document.write( "\n" ); document.write( "Since these two are said to be equal,
\n" ); document.write( "set them equal to each other and solve for x
\n" ); document.write( "--------------------------------------
\n" ); document.write( "6+2x=x-7 (subtract x from each side)
\n" ); document.write( "6+x=-7 (subtract 6 from each side)
\n" ); document.write( "x=-13
\n" ); document.write( "-------------- ----------------------\r
\n" ); document.write( "\n" ); document.write( "Now that we have the value of x,
\n" ); document.write( "replace x in the original equation and solve.\
\n" ); document.write( "6+2x=x-7
\n" ); document.write( "6+2(-13)=-13-7
\n" ); document.write( "6-26 =-20
\n" ); document.write( "-20=-20 CHECK!
\n" ); document.write( "-------------------------------
\n" ); document.write( "answer=-20
\n" ); document.write( " \n" ); document.write( "
\n" );
