Answer:
(5,10)
(3,6)
Step-by-step explanation:
The equation y=2x means that 2 multiplied by the first value would equal the second value, so this means that the second value is twice as much as the first value. This is not true for the first option because 8 is not twice of 16, and this is the same for (4,6), (4,2), and (1,3). Therefore (5,10) and (3,6) work.
No regrouping: 4.34 + 4.35
Regrouping (carrying): 4.93 + 3.76
y = -x + 1/3
+ x + x
--------------------------
x + y = 1/3
