A+S=200 OR A=200-S
\n" ); document.write( "6A+4S=940 NOW SUBSTITUTE (200-S) FOR A & SOLVE FOR S
\n" ); document.write( "6(200-S)+4S=940
\n" ); document.write( "1200-6S+4S=940
\n" ); document.write( "-2S=940-1200
\n" ); document.write( "-2S=-260
\n" ); document.write( "S=-260/-2
\n" ); document.write( "S=130 TICKETS SOLD TO STUDENTS THEN
\n" ); document.write( "200-130=70 ADULT TICKETS SOLD.
\n" ); document.write( "PROOF
\n" ); document.write( "6*70+4*130=940
\n" ); document.write( "420+520=940
