First choice

Step-by-step explanation:

When y = 4, x = -7 or 5

So only first choice is correct.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
