Sure, let's evaluate the expression step-by-step.
Given expression:
[tex]\[
6 \times \left[(18 + 17) \div 7 - 1 \right]
\][/tex]
Step 1: Calculate the sum inside the parentheses.
[tex]\[
18 + 17 = 35
\][/tex]
Step 2: Divide the sum by 7.
[tex]\[
35 \div 7 = 5.0
\][/tex]
Step 3: Subtract 1 from the division result.
[tex]\[
5.0 - 1 = 4.0
\][/tex]
Step 4: Multiply the result by 6.
[tex]\[
6 \times 4.0 = 24.0
\][/tex]
Thus, the value of the expression is:
[tex]\[
24.0
\][/tex]
