Your first step since you know the x=5 is to work the x to the 3rd power which would now be 5 to the 3rd power so that would be 5x5x5 which is 125
now your problem should be 2x?-12. so your next step would be 2x125 which is 250 so now your problem will be 250-12. do this and get the ans to your problem. Good Luck
