Question

How many true, real number solutions does the equation n + 2 = -16-5n have?solution(s)

Answer 1

The equation is

n + 2 = - 16 - 5n

By collecting like terms, we have

n + 5n = - 16 - 2

6n = - 18

Dividing both sides of the equation by 6, we have

6n/6 = - 18/6

n = - 3

It has only one solution
