- Answer:
n = - 1
- Step-by-step explanation:
Hi !
6 = - 2(10n + 7)
6 = - 20n - 14
20n = - 6 - 14
20n = - 20
n = - 20 : 20
n = - 1
6 = - 2(10×-1 + 7)
6 = - 2(-10 + 7)
6 = - 2(-3)
6 = 6 (true)
Good luck !
Answer:
n = -1 OR -1 = n
Step-by-step explanation:
6 = -2(10n +7)
First we remove the brackets by multiplying the inner numbers by -2
6 = -20n - 14
Then we add 14 on both sides
20 = -20n
We make n the subject and divide both sides by -20
n = -1 OR -1 = n
