Answer 3

To solve the equation 3.5y + y = 9.9, follow these steps:

Step 1: Combine the y terms on the left-hand side of the equation: 3.5y + y = 4.5y

Step 2: Now the equation becomes: 4.5y = 9.9

Step 3: To solve for y, divide both sides of the equation by 4.5: y = 9.9 / 4.5

Step 4: Calculate the result: y = 2.2

So, the value of y that satisfies the equation is y = 2.2.
