always start with the most inside parentheses or brackets and work your way out.
so it becomes
47-2[5-{(4x17) +(4x3)}]+6
47-2[5-(68+12)]+6
47-2[5-80]+6
47-2(-75)+6
convert the minus 2 into plus a negative 2 and multiply this times the negative 75
47+(-2)(-75)+6
two negatives multiplied together make a positive number
47 +(150) +6
47+150+6
197+6=203

(17+3)=20
4(20)=80
5-80=-75
2(-75)=-150
47-(-150)=47+150=197
197+6=203
=> 47-2[5-4(17+3)]+6=203
