Can someone explain to me how to do this please

I am not looking for answers I just need help understanding how to do this?

Solve the following equation: 5 + {6 + 2 x (3 + 9)} =
38
93
74
101
35

I have no clue what that random list of numbers means but...
order of operations: PEMDAS: Please Excuse My Dear Aunt Sally: Parantheses, Exponents, Multiplication+Division, Addition+Subtraction
look in the parantheses, you see another pair of parantheses, so look inside that. 3+9=12.
now you have (6+2x12) find the operation that comes first in PEMDAS, which is M in this case.
so multiply 2x12=24
now you have (6+24) just add.. and you end up with 30
now you have 5+30, which is 35
simply look at PEMDAS and find which operation comes first in your problem, then just follow. multiplication and division have equal priority I guess you could say. you just do which ever comes first. same goes with addition and subtraction. you do whichever one comes first, even if its subtraction first.

Do the operations in parenthesis first (3+9)
then multiplication 2 * (12)
then the brakcets 6 + 24
then addition 5+30 = 35

So parenthesis first, multiplication and division, then addition and subtraction
