Solve the following equation:
$$48÷[35-\{30-(31-26÷2\times 4)\}]=?$$

Following the BODMAS rule, evaluate the components step-by-step beginning from the innermost parentheses:
1. Inside the round brackets, evaluate division and multiplication first:

$$26÷2=13$$

$$13\times 4=52$$

Substitute this back to finish the round bracket evaluation:

$$31-52=-21$$

2. Substitute the evaluated value into the curly braces:

$$\{30-(-21)\}=\{30+21\}=51$$

3. Substitute this result into the square brackets:

$$[35-51]=-16$$

4. Perform the final outer division:

$$48÷(-16)=-3$$

Hence, the answer is $-3$.
