Hope this helps!
In order to solve this we will have to apply PEMDAS rule which is as follows:
P
Parentheses first
E
Exponents (ie Powers and Square Roots, etc.)
MD
Multiplication and Division (left-to-right)

Addition and Subtraction (left-to-right)
7+8(3.2.2)
Step 1:
Here we will solve the parenthesis first :
multiplying 3.2.2 =12
so we have 7+8(12)
Step 2:
now we multiply 12*8 here
12*8=96
7+96
Step 3:
addition of 7 and 96 gives us 103
Answer : 7+8(3.2.2) = 103
8n + 12 +(-9) -(-6n)
12 + -9 = 12-9 = 3
8n - (-6n) = 8n + 6n = 14n
The equation becomes 14n + 3
