Are you trying to say 17 + 6 + (7-9) ? = 21
Use BODMAS/BIDMAS/PEDMAS: 9 + 6(22 + 4) = 9 + 6(26) = 9 + 6 × 26 = 9 + 156 = 165

14 plus 8 minus 9 times 6 is equal to -32.
Are you trying to say 17 + 6 + (7-9) ? = 21
(6 x 9) + 6 + 9 = 69
9
-2x = 12 so x = -6 giving -30 + 9 = -42 + 21. Both sides = -21.
Use BODMAS/BIDMAS/PEDMAS: 9 + 6(22 + 4) = 9 + 6(26) = 9 + 6 × 26 = 9 + 156 = 165

6+6+6+6+6+6+6+6+6 =54 This can also be written as 6*9. That is because 6 is added 9 times.
