(у+47)-17=39

To solve the equation for \( y \), we need to isolate \( y \) on one side of the equation. Here's how we do it step-by-step:

Given equation: \[ (y + 47) - 17 = 39 \]

First, we can combine the constant terms on the left side of the equation (+47 and -17): \[ y + (47 - 17) = 39 \] \[ y + 30 = 39 \]

Now we will subtract 30 from both sides of the equation to isolate \( y \): \[ y + 30 - 30 = 39 - 30 \] \[ y = 9 \]

So the value of \( y \) that satisfies the equation is 9.
