Answer:
n=4
Step-by-step explanation:
First you subtract 8 from 15 which gives you 7 so it is n+3=7. then you subtract 3 from 7 which gives you 4.
n = 4 and n = -10
Explanation:
l n + 3 l + 8 = 15
l n + 3 l = 7
Two solutions
n + 3 = 7
n = 4
and
n + 3 = -7 (since we are dealing with absolute numbers, one side has to be multiplied by -1)
n = -10
