Let's solve each equation step by step.

1. **Equation: \(18 + (80 - x) = 22\)**

Simplify inside the parentheses:
\[
18 + 80 - x = 22
\]

Combine like terms:
\[
98 - x = 22
\]

Isolate \(x\) by subtracting 98 from both sides:
\[
-x = 22 - 98
\]
\[
-x = -76
\]

Multiply both sides by -1 to solve for \(x\):
\[
x = 76
\]

2. **Equation: \(7x + x + 85 = 120\)**

Combine like terms:
\[
8x + 85 = 120
\]

Isolate \(x\) by subtracting 85 from both sides:
\[
8x = 120 - 85
\]
\[
8x = 35
\]

Divide both sides by 8 to solve for \(x\):
\[
x = \frac{35}{8}
\]
\[
x = 4.375
\]

3. **Equation: \(4x + x + 5x + x = 27\)**

Combine like terms:
\[
11x = 27
\]

Divide both sides by 11 to solve for \(x\):
\[
x = \frac{27}{11}
\]
\[
x \approx 2.4545
\]

So, the solutions are:
1. \(x = 76\)
2. \(x = 4.375\)
3. \(x \approx 2.4545\)
