Equation 1: \"B+=+A+%2B+170\"
\n" ); document.write( "Equation 2: \"A+%2B+B+=+1510\"
\n" ); document.write( "-------------------------------
\n" ); document.write( "Note that equation 1 is already solved for B
\n" ); document.write( "Plug (A + 170) into equation 2 for B
\n" ); document.write( "Equation 2: \"A+%2B+B+=+1510\"
\n" ); document.write( "\"A+%2B+%28A+%2B+170%29+=+1510\"
\n" ); document.write( "Combine like terms
\n" ); document.write( "\"2A+%2B+170+=+1510\"
\n" ); document.write( "Subtract 170 from both sides.
\n" ); document.write( "\"2A+=+1340\"
\n" ); document.write( "Divide both sides by 2
\n" ); document.write( "\"highlight%28A+=+670ft%29\"
\n" ); document.write( "--------------------------
\n" ); document.write( "No go back and solve for B
\n" ); document.write( "Equation 1: \"B+=+A+%2B+170\"
\n" ); document.write( "\"B+=+%28670%29+%2B+170\"
\n" ); document.write( "\"highlight_green%28B+=+840ft%29\"
\n" ); document.write( "
\n" );
