Do you mean “evaluate when x = 4”? If so:
7x + 14 − 2 evaluated at x = 4 gives 7·4 + 14 − 2 = 28 + 14 − 2 = 40.
If you meant the Iverson bracket [x=4] (which equals 1 when x=4 and 0 otherwise), then with x = 4 the expression 7x + 14 − 2[x=4] is also 40.
If you meant something else by the brackets (e.g. floor function [x]), tell me and I’ll recompute.
