Question 796849
the answer would be A
10/2 = 5, so 10 = 2(x) would be the correct equation

lets solve b though to help understand...

10 = 2 + 2(x)

subtract 2 from both sides

8 = 2(x)

divide both sides by 2

4 = x

2 times 4 = 8
santha is 10 years old, not 8 years old.   if santha was 8 years old then B would work.
