It's not perfectly clear to me, but
I assume that the problem is , and I'll solve that.

If I had a choice, I would not solve that system by substitution.
--> -->
Substituting for in we get
--> --> --> --> --> .
Then, substituting for in , we get
--> --> .

If I could choose how to solve it,
I would first transform the equations,
so as to get equivalent equations without fractions.
--> (multiplying everything times 6)
--> (multiplying everything times 12)
Then I would add both equations to get
--> .
I would also subtract the second equation from the first one to get
--> .

IF THE PROBLEM WAS
,
That's the same as
.
That could be solve the same way for and to get
and
Then the solutions would be and .
