How i do this yall..?

Solve for nn by simplifying both sides of the equation, then isolating the variable.

n=4, −2

We know that a modulus gives us the absolute value of a number

Hence,  this modulus will give a positive value, regardless of the actual value in the modulus

| -1 + n | = 3

(-1 + n) or (1 - n) = 3 This tells us that either one of the values will          give us the same answer

-1 + n = 3   or   1 - n = 3

n = 4          or   n = -2  

you should at least use a calculater
