Two interpretations:
1) 8+(2/6)(22+6x)=58
8+(1/3)(22+6x)=58
(22+6x)/3=50
22+6x=150
6x=150-22=128, x=128/6=64/3=21 1/3=21.67 to nearest 100th
OR
2) 8+2/(6(22+6x))=58
8+1/(3(22+6x))=58
1/(3(22+6x))=50
3(22+6x)=1/50
22+6x=1/150
6x=1/150-22=1/150-3300/150=-3299/150
x=-3299/900=-32.99/9=-3.666... =-3.67 to nearest 100th
