To solve the equation \( x + (x + 2) + (x + 4) = 120 \):
1. Combine like terms on the left side:
\[
x + x + 2 + x + 4 = 120 \implies 3x + 6 = 120
\]
2. Subtract 6 from both sides:
\[
3x = 120 - 6 \implies 3x = 114
\]
3. Divide both sides by 3:
\[
x = \frac{114}{3} \implies x = 38
\]
Now we can find the three integers:
- 1st integer = \( x = 38 \)
- 2nd integer = \( x + 2 = 40 \)
- 3rd integer = \( x + 4 = 42 \)
The largest of the three integers is:
**42**
The correct response is:
**42**
