So the question is asking us to determine if those 4 equations in the table is equivalent to 12x + 36y when simplified.
1. (10x + 36y) +(2x + y)
12x + 37y
No
2. 6(2x + 6y)
12x + 36y
Yes
3. 3(4x + 5y) + 7(3y)
12x + 15y + 21y
12x + 36y
Yes
4. 5x + 5y + x + y + 6x + 6y
12x + 12y
No
Hope this helps and have a great day!
