X + 5y + 2 - 7x + 5y + 2y - 7x
First collect like terms (the numbers that have the same letters after them):
x - 7x - 7x = -13x
5y + 5y + 2y = 12y
Then put these back into the expression:
2 - 13x + 12y
Complete Question

Answer:
a
No singular point due to the exponent in the solution
The interval is 
b
NONE
Step-by-step explanation:
From the question we are told that

The generally solution is mathematically represented as

=> 
integrating both sides

=> 
=> 
=> 
Here 
=> 
From the above equation we see that the domain for x has no singular point the interval is

Also there is no transient term in the general solution obtained because as
there no case where
