5x - 9y = 11
\n" ); document.write( "3x + 7y = 19
\n" ); document.write( ":
\n" ); document.write( "Using the elimination method to eliminate x:
\n" ); document.write( "Mult the 1st equation by 3
\n" ); document.write( "Mult the 2nd equation by 5:
\n" ); document.write( ":
\n" ); document.write( "15x - 27y = 33
\n" ); document.write( "15x + 35y = 95
\n" ); document.write( "---------------- Subtract
\n" ); document.write( "0x - 62y = -62
\n" ); document.write( "Divide both sides by -62
\n" ); document.write( "y = -62/-62
\n" ); document.write( "y = +1
\n" ); document.write( ":
\n" ); document.write( "Find x; substitute 1 for y in the 1st equation:
\n" ); document.write( "5x - 9(1) = 11
\n" ); document.write( "5x - 9 = 11
\n" ); document.write( "5x = 11 + 9
\n" ); document.write( "5x = 20
\n" ); document.write( "x = 20/5
\n" ); document.write( "x = +4:
