The sum of three consecutive even integers (3 even integers in a row) is 120.
Use the following setup and given equation to find your solution:
1st integer = x
2nd integer = x+2
3rd integer = x+4
Equation: x+(x+2)+(x+4)=120
Solve the equation above. What is the largest of the three integers?

Let's solve the equation provided:
The equation is:
\[
x + (x + 2) + (x + 4) = 120
\]
Combining like terms:
\[
x + x + 2 + x + 4 = 120
\]
\[
3x + 6 = 120
\]
Next, we will isolate \(x\):
\[
3x = 120 - 6
\]
\[
3x = 114
\]
\[
x = \frac{114}{3}
\]
\[
x = 38
\]
Now we can find the three consecutive even integers:
1st integer: \(x = 38\)
2nd integer: \(x + 2 = 38 + 2 = 40\)
3rd integer: \(x + 4 = 38 + 4 = 42\)
Now we have the integers: 38, 40, and 42. The largest of these three integers is **42**.
Thus, the answer is:
**42**
The equation is:
\[
x + (x + 2) + (x + 4) = 120
\]
Combining like terms:
\[
x + x + 2 + x + 4 = 120
\]
\[
3x + 6 = 120
\]
Next, we will isolate \(x\):
\[
3x = 120 - 6
\]
\[
3x = 114
\]
\[
x = \frac{114}{3}
\]
\[
x = 38
\]
Now we can find the three consecutive even integers:
1st integer: \(x = 38\)
2nd integer: \(x + 2 = 38 + 2 = 40\)
3rd integer: \(x + 4 = 38 + 4 = 42\)
Now we have the integers: 38, 40, and 42. The largest of these three integers is **42**.
Thus, the answer is:
**42**
