If we multiply the 1st equation by 5 and subtract the 2nd from it, we have:
\n" ); document.write( "32y^2 - 16y - 48 = 0
\n" ); document.write( "Divide through by 16 and factor:
\n" ); document.write( "(2y - 3)(y + 1) = 0
\n" ); document.write( "y = 3/2, y = -1
\n" ); document.write( "Using the 1st equation to solve for x, we get:
\n" ); document.write( "x^2 - 2x - 4 - 8 - 2 = 0
\n" ); document.write( "x^2 - 2x - 14 = 0 -> x= -2.8729833 and x= 4.8729833
\n" ); document.write( "x^2 - 2x - 4(3/2)^2 + 8(3/2) - 2 = 0 -> x^2 - 2x + 1 = 0 -> (x-1)(x-1) = 0
\n" ); document.write( "This gives x = 1, multiplicity 2
\n" ); document.write( "
