Children Line Position Ema

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

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
