Assume all angles are in a triangle. we get
\n" ); document.write( " $\"3x+%2B+%28x%2B4%29+%2B+%282y-12%29+=+180\"$
\n" ); document.write( "step 1 - combine like terms to get
\n" ); document.write( " $\"4x+-8+%2B+2y+=+180\"$
\n" ); document.write( "step 2 - add 8 and subtract 4x from both sides to get
\n" ); document.write( " $\"2y+=+188+-+4x\"$
\n" ); document.write( "here there are many values of X and Y that work.
\n" ); document.write( "--
\n" ); document.write( "Assume that one of the angles = another angle, for example angle 1 = angle 2, then we can say
\n" ); document.write( "3x = x + 4
\n" ); document.write( "2x = 4
\n" ); document.write( "x = 2
\n" ); document.write( "Now in angle 3, all we have is a Y, so
\n" ); document.write( "3 = 2y - 12
\n" ); document.write( "15 = 2y
\n" ); document.write( "y = 7.5
\n" ); document.write( "Here x = 2 and y = 7.5
\n" ); document.write( "--
\n" ); document.write( "not sure how the angles are related. \n" ); document.write( "

\n" );
