Answer:
a is positive and b is negative
Step-by-step explanation:
ok, since |a-b| is the absolute value of a-b, so whatever a-b is gonna be it must end up positive
a + b can't both be positive because then a+b not equal to a-b
a cant be negative ever because that would conflict with the absolute value part of the right side of the equation
thus a must be positive and b must be negative
