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)
The ordered pair is (1, 3).
The ordered pair is (5, 4).
There are an infinite number of ordered pairs that satisfy the equation.
