(у+47)-17=39

To solve the equation for у, we can start by isolating у on one side. Here's how you do it:

Given: (у + 47) - 17 = 39

Combine like terms: у + (47 - 17) = 39 у + 30 = 39

Now, to isolate у, subtract 30 from both sides of the equation: у + 30 - 30 = 39 - 30 у = 9

So, the solution to the equation is у = 9.
