Question

? × [1 - 1/6(4+ 2^3)] = 7

Answer 1

To solve the equation \( ? \times \left[ 1 - \frac{1}{6}(4 + 2^3) \right] = 7 \), we'll first simplify the expression inside the brackets.

1. Calculate \( 2^3 \):
\[
2^3 = 8
\]

2. Substitute \( 8 \) back into the expression:
\[
4 + 2^3 = 4 + 8 = 12
\]

3. Now, substitute \( 12 \) into the equation:
\[
1 - \frac{1}{6}(12)
\]

4. Calculate \( \frac{1}{6}(12) \):
\[
\frac{12}{6} = 2
\]

5. Now substitute \( 2 \) back into the equation:
\[
1 - 2 = -1
\]

Now we can rewrite the equation as:
\[
? \times (-1) = 7
\]

To find \( ? \):
\[
? = \frac{7}{-1} = -7
\]

So, the value of \( ? \) is \( \boxed{-7} \).
