The correct equation to represent the scenario where the two videos have the same number of views after \( x \) days is:
\[ 2,130 + 80x = 1,800 + 90x \]
This can be rearranged to:
\[ 80x - 90x = 1,800 - 2,130 \]
Which simplifies to:
\[ -10x = -330 \]
So, in the format provided in your options, the closest correct expression is:
\[ 80x - 2,130 = 90x - 1,800 \]
So, the correct choice from the list is:
80x − 2,130 = 90x − 1,800
