first, according to order of operations we do what is in the parenthesis first:
( 4 x 2 +5)
(8+5)= 13
now rewrite it using this answer:
3x + 2 - 13
next according to order of operations, multiply 3x2
6+2-13 now since its all add/subtract according to order of operations just go from left to right
8-13= -5
-5 is your answer
