No.
As I understand your problem, x is an unknown.
42+x-3(x-2)+11
42 + x - 3x + 6 + 11
42 + 17 - 2x
59 - 2x
Is this the right answer? 42+x-3(x-2)+11
42+8-3(8-2)+11
47×6+11
282+11
293

No x is 8
In that case, things are still a bit off:
42+8-3(8-2)+11
42+8-3(6)+11
42+8-18+11
50-18+11
32+11
43
multiplication comes before addition
42+8-3(8-2)+11
42+8-3(6)+11
42+8-18+11
50-18+11
32+11
43
