X-y=34
x+y=338
We can use elimination in this problem.
2x=372
x=186
186+y=338
y=338-186
y=152
Answer:
A.
Step-by-step explanation:
From the given information:
If A = m × n matrix
where;
b is a vector in 
Then; the statement that doesn't fit and is not related to the other three from the given options is Option A.
This is because the statement in Option A appears to be inconsistent. For the model Ax=b to have a solution, A must be non-singular and b must be in A's column space.
Option c and d are equivalent, also option b and c are equivalent.
Sorry I don't what the answer would be for A. But B would be (3,13)
