Is there a solution to such a mathematical problem?

Question

Mathematics

Probably a question from school mathematics, but my head doesn’t boil in the evening :-) I don’t even know how to write it correctly, don’t swear
There is an equation
(a1 + b1 + c1) + (a2 + b2) + (a3 + b3) + a4 = x +y, all values ​​are known.
It is necessary to find the value of each coefficient (a, b, c) for:
(a1+b1+c1)+(a2+b2)+(a3+b3)+a4 = x
(a1+b1+c1)+(a2+b2) +(a3+b3)+a4 = y

Answer 2

1) there is no a, b, c in the second record. Yes, the first one too.
2) there are no coefficients in the second entry
