Children Line Position Ema

There are 29 children in the class. The number of children enrolled in front of Ema is six less than behind her. How old is Ema?

Final Answer:

a =  12

Step-by-step explanation:


29 = a+b
a-1 = b-6

a+b = 29
a-b = -5

Row 2 - Row 1 → Row 2
a+b = 29
-2b = -34


b = -34/-2 = 17
a = 29-b = 29-17 = 12

a = 12
b = 17
