Starting with
\n" ); document.write( "2a - 5/7 = 3a + 4/9
\n" ); document.write( "Group like terms
\n" ); document.write( "-5/7 - 4/9 = 3a - 2a
\n" ); document.write( "Create common denominator on the left
\n" ); document.write( "-5/7(9/9) - 4/9(7/7) = a
\n" ); document.write( "-45/63 - 28/63 = a
\n" ); document.write( "a -73/63 = -1 10/63
\n" ); document.write( "...
\n" ); document.write( "Proof
\n" ); document.write( "2(-73/63) - 5/7 = -146/63 - 5/7(9/9) = -146/63 - 45/63 = -191/63
\n" ); document.write( "3(-73/63) + 4/9 = -219/63 + 4/9(7/7) = -219/63 + 28/63 = -191/63
