Answer:
4
+ 8 x - 435=0
Step-by-step explanation:
Let x be any natural number
Let the age of Bill= 2 x+ 1 years (Since age is odd integer)
Than, age of a Susan= 2 x + 3 years
Since ages are consecutive odd integers
According to question
(2 x+1)(2 x+ 3)= 438
4
+ 8 x + 3 = 438
4
+ 8 x + 3 - 438 =0
4
+ 8 x - 435=0
This equation can be used to find the ages of both
Hence, the correct answer is 4
+ 8 x - 435=0
