Is this the right answer? 42+x3(x2)+11
42+83(82)+11
47×6+11

293

No.
As I understand your problem, x is an unknown.
42+x3(x2)+11
42 + x  3x + 6 + 11
42 + 17  2x
59  2x

In that case, things are still a bit off:
42+83(82)+11
42+83(6)+11
42+818+11
5018+11
32+11
43
multiplication comes before addition
