12(9-3x) + 2x = 516
108 - 36x + 2x = 516
-34x = 516-108
-34x = 408
x = -408/34
x = - 12
108 - 36x + 2x = 516
-34x = 516-108
-34x = 408
x = -408/34
x = - 12
12(9-3x) + 2x = 516
Now, open the bracket
108 - 36x + 2x = 516
-36x + 2x = 512
-34x = 516-108
-34x = 408
x = -408/34
x = - 12
Now, open the bracket
108 - 36x + 2x = 516
-36x + 2x = 512
-34x = 516-108
-34x = 408
x = -408/34
x = - 12
