Answer 2

It looks like you've provided a sequence of equations where certain digits are missing and replaced with underscores. The pattern here seems to involve arranging the digits in a specific manner to satisfy the given equations. Let's try to figure out the pattern:

49_7_8_ = 5664_2_4 = 863_9_23 = 3095_5_30 = 70

It seems like there's a relationship between the digits that allows them to form valid equations. One possible pattern is:

491748 = 5664824 = 86359723 = 30957530 = 70

In each equation, the digits are placed in such a way that they form valid arithmetic expressions. However, I must note that this is just one possible interpretation of the pattern based on the information provided. If there's a different pattern or context you have in mind, please provide more details so I can assist you accurately.
