975×(у-615)=12675

To solve the equation \( 975 \times (y - 615) = 12675 \), follow these steps:

1. Divide both sides of the equation by 975 to isolate the term with \( y \):

   \[ y - 615 = \frac{12675}{975} \]

2. Calculate the right side:

   \[ \frac{12675}{975} = 13 \]

3. Now, the equation simplifies to:

   \[ y - 615 = 13 \]

4. Add 615 to both sides to find \( y \):

   \[ y = 13 + 615 \]

5. Thus,

   \[ y = 628 \]

The solution to the equation is \( y = 628 \).
