It tells you that x is 3 so first multiply 7 and 3 you get 21 subtracted by 6 is 15 divided by 3 is 5 plus 4 is 9 you set that aside then focus in the parenthesis 2 time 3 is 6 plus 8 is 14 multiplied by 9 because whatever number is next to the parenthesis without a symbol between it you usually multiply it and you get 12. Hope this helped.
