The number on the line is 110
The expressions are given as:
Represent the blank with x.
So, we have:
Expression 2: x + 200r
When both expressions are equivalent, we have:
[tex]x + 200r = 200r - (-110)[/tex]
Open the bracket
[tex]x + 200r = 200r + 110[/tex]
Subtract 200r from both sides
[tex]x = 110[/tex]
Hence, the number on the line is 110
