And so on the cycle repeats every four numbers. To find the value of
we can find the remainder of 96/4=0. So 
The given expression is

Factoring

Since 

The required value is 0
Step-by-step explanation:
8x+3y=18
subject y according y=mx+c
y=8/3x-6
(-9,-13)
substitute -9 to y=8/3x-6
-13=8/3×(-9)+c
11=c
y=8/3x+11
4,408,730 = 4,000,000 + 400,000 + <span>8,000 + 700 + 30 </span>
