Step-by-Step Solution

Verified
Answer
-4x + 11y
1Step 1: Identify like terms
Here, like terms are those that contain same variables. So, 13x and -17x are like terms as they both contain 'x'. Similarly, -9y and 20y are like terms as they both contain 'y'.
2Step 2: Combine like terms
Add or subtract the coefficients (the numerical factors) of like terms. This gives us: (13x - 17x) + (-9y + 20y)
3Step 3: Simplify
Performing the operations, resulting in -4x + 11y
