Correct!
\n" ); document.write( "Angle x + Angle y =180
\n" ); document.write( "Angle y = 3x+4, so
\n" ); document.write( "x+(3x+4)=180 [solve for x]
\n" ); document.write( "3x+4=180
\n" ); document.write( "3x=180-4
\n" ); document.write( "3x=176
\n" ); document.write( "x=44
\n" ); document.write( ".
\n" ); document.write( "Plugging in the values
\n" ); document.write( "44+[3(44)+4]=180
\n" ); document.write( "44+(132+4)=180
\n" ); document.write( "180=180 [checks out]
\n" ); document.write( "
\n" ); document.write( "
\n" );
