Alternative hypothesis (H1):
And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no

Step-by-step explanation:
Given
Ax - bx - y = z ( add y to both sides )
Ax - bx = z + y ← factor out x from both terms on the left side
x(A - b) = z + y ← divide both sides by (A - b)
x =
