Supplementary angles add to 180 degrees.
\n" ); document.write( "let smaller angle be x, then
\n" ); document.write( "3x+5=2y
\n" ); document.write( "x+y=180
\n" ); document.write( "Multiply second equation by -3 then add it to the first one
\n" ); document.write( "3x-2y=-5
\n" ); document.write( "-3x-3y=-540 When you add them, the x's cancel out (because they add to zero)
\n" ); document.write( "**********
\n" ); document.write( "-5y=-545 divide each side by -5
\n" ); document.write( "y=109
\n" ); document.write( "if y is 109 then x would be
\n" ); document.write( "x=180-109=71
\n" ); document.write( "So the angles are 71 and 109
\n" ); document.write( "
\n" );
