Let's denote the number of listens for the first song as \( L_1 \) and for the second song as \( L_2 \).
-
The initial listens for the first song: \[ L_1 = 700 + 52d \] where \( d \) is the number of days since the beginning of the month.
-
The initial listens for the second song: \[ L_2 = 600 + 56d \]
We want to find the value of \( d \) when the two songs have the same number of listens: \[ 700 + 52d = 600 + 56d \]
Now, we can solve this equation for \( d \).
-
Subtract \( 52d \) from both sides: \[ 700 = 600 + 4d \]
-
Subtract 600 from both sides: \[ 100 = 4d \]
-
Divide both sides by 4: \[ d = 25 \]
Therefore, the two songs will have the same number of listens after 25 days.
