Answer:
the answer is 7
Step-by-step explanation:
the order of operation is
P= parentheses
E= exponent
M= multiplication
D= division
A= addition
s= subtraction
so that means first you do what is in the () so 12÷ 6= 2
now the next step would be divisions so that mean 15 ÷ 5 =3
now we have to put these two answers back in to the equation 3+6-(2) then add 3 and 6 you should get 9 now subtract 2 and you get 7
