∙ 12y ago2x + 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)
