It would seem the only solution is 0, but

and the denominator of the fraction can't be equal zero, therefore there's no solution.
The question isn’t complete
Answer:

Step-by-step explanation:
Rearrange the equation so b is the independent variable.
To get 'b' as a independent variable , we need to get 'a' alone
WE need to solve for 'a' so that 'a' depends on variable b and 'b' becomes independent variable
4a+b=−52
To get 'a' alone , subtract 'b' from both sides
4a = -52-b
Divide by 4 on both sides
