Answer is n = -6
Solving for n means you need to find the value of n, so rearrange the expression to get n on its own.
First expand the brackets, so:
2(n + 5) = -2
Becomes
2n+10 = -2
Then get 10 to the other side.
2n = -10 -2
2n = -12
Afterwards, divide 2n by 2 to get n on its own.
(2/2)n = -12/2
n = -6
So n = -6.
