Answer 3

To solve the equation "Y•20-200=400," I assume you meant to use the multiplication symbol (•) to represent multiplication. In standard notation, we use the asterisk (*) for multiplication.

Let's rewrite the equation using the correct notation:

Y * 20 - 200 = 400

To solve for Y, we can follow these steps:

Step 1: Add 200 to both sides of the equation to isolate the term with Y:

Y * 20 - 200 + 200 = 400 + 200

Simplifying:

Y * 20 = 600

Step 2: Divide both sides of the equation by 20 to solve for Y:

(Y * 20) / 20 = 600 / 20

Simplifying:

Y = 30

Therefore, the solution to the equation "Y•20-200=400" is Y = 30.
