Answer:
36x + 98y
Explanation:
We have to simplify the given expression below: 
The expression is (40x + 52y) + (- 14x + 46y) 
= 40x + 52y - 14x + 46y 
{We have to add the like terms and for that opening the brackets} 
= (40x - 14x) + (52y + 46y) 
{Separating the x terms and y terms and keeping them in brackets} 
= 36x + 98y (Answer)
