To do this do the work in the brackets first. There are two parentheses.  First solve 6/3.  This gives you two.  Now you add it to 7 (3+4) to get 9.  Now you want to add 30 by 9.  The answer is 39.
Solve the ones inside the parenthesis.
6÷3 = 2
4+3=7  add 7 and 2 which is 9
now since everything inside the brackets and parenthesis is solved add the 30 to 9
 30+9 = 39
