Answer 3

Sure, I'd be happy to help you solve the equation. Let's go step by step:

The given equation is: Y - (40 + 20) = 20.

Step 1: Simplify the expression inside the parentheses: 40 + 20 = 60.

Now the equation becomes: Y - 60 = 20.

Step 2: Isolate the variable Y on one side of the equation. To do this, we'll get rid of the constant term (-60) on the left side by adding 60 to both sides of the equation:

Y - 60 + 60 = 20 + 60.

Y = 80.

Step 3: Check the solution: To verify the solution, we'll substitute Y back into the original equation:

Y - (40 + 20) = 20, 80 - (40 + 20) = 20, 80 - 60 = 20, 20 = 20.

The equation holds true, so the solution Y = 80 is correct.
