Best Answer

2x + 4y = 16 <=> 2x + 4y - 16 = 0

2x - 4y = 0

2x - 4y = 2x + 4y - 16

-8y = -16

y = 2

Substituting the known value for y in either of the original equations enables x to be determined.

2x + (4*2) = 16 : 2x = 16 - 8 : x2x = 8 : x = 4

2x - (4*2) = 0 : 2x - 8 = 0 : 2x = 8 : x = 4.

The ordered pair satisfying both equations is (4,2)
