From the question,
We are to determine the expression which is equivalent to the given expression.
First, we will simplify the given expression
The given expression is (12x−5y−1)+(17y−4−13x−3y)
The expression can be simplified as shown below
(12x−5y−1)+(17y−4−13x−3y)
12x−5y−1+17y−4−13x−3y
Collect like terms
12x−13x+17y−5y−3y−4−1
This becomes
-x+9y−5
The simplified expression is -x+9y−5
Hence, the expression that is equivalent to the given expression is -x+9y−5. The correct option is 2. −x+9y−5
