How do I get rid of the neg 16?

n + (5/-16) = -1 original equation

n - (5/16) = -1 took the negative from the denominator, moved the numerator, no change of value

n = -1 + 5/16 added 5/16 to both sides of equation

n = -(16/16) + 5/16 changed -1 to -(16/16), equal value

n = 5/16 - (16/16) reversed the order

n = -(11/16) did the arithmetic
