Supplementary angles add to 180. Call the angles x and y. x+y=180


\n" ); document.write( "x = 4y-3 (three less than 4 times y). Substitute this for x into the first equation and solve it.


\n" ); document.write( "4y-3+y = 180


\n" ); document.write( "5y = 183


\n" ); document.write( "y=36.6


\n" ); document.write( "x = 180-36.6 = 143.4 \n" ); document.write( "
