let
x---------> Aviva’s age
y--------->Kanti’s age
z--------> Lakshmi’s age
we know that
y=x-3-----> equation 1
z=2*y-----> equation 2
substitute equation 1 in equation 2
z=2*(x-3)
so
Aviva’s age------> x
Kanti’s age-------> x-3
Lakshmi’s age----> 2*(x-3)
therefore
the answer is the option
b) 2(x-3)

Answer:
12
Step-by-step explanation:
13 + 6 + 2x -18 = 4x - 29
19 + 2x -18 = 4x -29
2x + 1 = 4x - 29
30 = 2x
15 = x
CD = 2(15) -18
CD = 30 -18
CD = 12
