Answer:
-2b^2+3b
Step-by-step explanation:
You just have to add like terms, which is the single numbers, the numbers with just the variables, and the numbers with variables that are squared.
we have

Let's Isolate the variable y in each of the cases and then compare with Fiona's equation to determine the solution of the problem
case A) 
Multiply by
both sides


Divide by
both sides

therefore
the case A) is not equal to Fiona's equation
case B) 
Multiply by
both sides


Divide by
both sides

therefore
the case B) is not equal to Fiona's equation
case C) 
Multiply by
both sides


Divide by
both sides

therefore
the case C) is not equal to Fiona's equation
case D) 
Multiply by
both sides


Divide by
both sides

therefore
the case D) is equal to Fiona's equation
<u>the answer is</u>
