X is 5 in this case!!!!hope it helps
Answer:
x = ± 2
Step-by-step explanation:
Given
x² + 5 = 3x² - 3 ( subtract x² + 5 from both sides )
0 = 2x² - 8 ( add 8 to both sides )
8 = 2x² ( divide both sides by 2 )
4 = x² ( take the square root of both sides )
x = ± = ± 2

There are three in the millions place and 806 in the thousands. There are no numbers in the hundreds so you place zeros.
Divide the number of actual pages by 2.
