Answer 2

To solve the equation 9-7y = 2.5-3y, we can follow these steps:

1. First, let's simplify the equation by combining like terms. Subtract 2.5 from both sides: 9 - 7y - 2.5 = 2.5 - 3y - 2.5 6.5 - 7y = -3y

2. Next, let's isolate the variable y on one side of the equation. Add 7y to both sides: 6.5 - 7y + 7y = -3y + 7y 6.5 = 4y

3. Now, let's solve for y by dividing both sides of the equation by 4: 6.5/4 = 4y/4 1.625 = y

Therefore, the solution to the equation is y = 1.625.
