No — they are not equivalent.

Work:
- Left expression: 2(x − 1) + 18 = 2x − 2 + 18 = 2x + 16.
- Right expression: 6(x + 3) − 4x − 6 = 6x + 18 − 4x − 6 = 2x + 12.

Since 2x + 16 ≠ 2x + 12 (subtracting 2x gives 16 ≠ 12), the two expressions are different for every x. For example, at x = 0 the left equals 16 while the right equals 12. Thus they are not equivalent.
