You can put this solution on YOUR website!
First, we make two equations
\n" ); document.write( "3x + 2y + 6x + y = 180
\n" ); document.write( "8x - y + 3x + 2y= 180
\n" ); document.write( "==================================
\n" ); document.write( "next, we combine like terms, multiply equation 2 by 3, and add the two equations
\n" ); document.write( "9x + 3y = 180
\n" ); document.write( "11x + y = 180
\n" ); document.write( "-33x -3y = -540
\n" ); document.write( "-24x = -360
\n" ); document.write( "Solve for x
\n" ); document.write( "x = 15
\n" ); document.write( "equation 1
\n" ); document.write( "Solve for y.
\n" ); document.write( "9(15) + 3y = 180
\n" ); document.write( "135 + 3y = 180
\n" ); document.write( "3y = 45
\n" ); document.write( "y = 15
\n" ); document.write( "=====================================================
\n" ); document.write( "angle 1 = 8(15) - 15 = 105 degrees.
\n" ); document.write( "angle 2 = 3(15) + 2(15) = 75 degrees
\n" ); document.write( "angle 3 = 6(15) + 15 = 105 degrees.
\n" ); document.write( "75 degrees + 105 degrees = 180 degrees.
\n" ); document.write( "105 degrees + 75 degrees = 180 degrees.
\n" ); document.write( "This does check.
