The interior angles of a parallelogram add up to 180 deg
\n" ); document.write( "4y+x=180\r
\n" ); document.write( "\n" ); document.write( "2y+5x-180=180
\n" ); document.write( "2y+5x=360\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4y+x=180
\n" ); document.write( "2y+5x=360 multiply the equation by -2 and to the other equation
\n" ); document.write( "-4y-10x=-720\r
\n" ); document.write( "\n" ); document.write( "-9x=-540\r
\n" ); document.write( "\n" ); document.write( "/-9
\n" ); document.write( "x=54
\n" ); document.write( "solve for y\r
\n" ); document.write( "\n" ); document.write( "4y+x=180
\n" ); document.write( "4y+54=180
\n" ); document.write( "4y=136
\n" ); document.write( "/4
\n" ); document.write( "y=39
\n" ); document.write( " \n" ); document.write( "
\n" );
