(у+47)-17=39

To solve for у in the equation (у + 47) - 17 = 39, you would first combine like terms inside the parentheses and simplify the equation. However, since the parentheses are not changing the operation here (there is nothing in front of them indicating multiplication or division), you can just remove the parentheses.

So the simplified equation becomes:

у + 47 - 17 = 39

Now, you combine the constants. 47 - 17 = 30, so the equation becomes:

у + 30 = 39

Next, you need to isolate the variable у by subtracting 30 from both sides of the equation:

у + 30 - 30 = 39 - 30

This simplifies to:

у = 9

So the solution for у is 9.
