5x - 12y = 207
\n" ); document.write( "5x - 11y = 206 subtract this equation
\n" ); document.write( "-----------------------
\n" ); document.write( "-y=1 answer
\n" ); document.write( "5x-12*-1=207
\n" ); document.write( "5x+12=207
\n" ); document.write( "5x=207-12
\n" ); document.write( "5x=195
\n" ); document.write( "x=195/5
\n" ); document.write( "x=39 answer.
\n" ); document.write( "proof:
\n" ); document.write( "5*39-11*-1=206
\n" ); document.write( "195+11=206
\n" ); document.write( "206=206\r
