To solve the equations:

1) 4x - 11 = x + 1

Combine like terms
4x - x = 11 +
3x = 1
Divide by 3
x = 4

2) (1/6)x + 3 = x

Multiply by 6 to clear the fraction
x + 18 = 6
Subtract x from both sides
18 = 5
Divide by 5
x = 3.6

3) (1/x) + 2 = 0.7/4.2

To simplify the right side of the equation
0.7/4.2 = 0.16667

Substitute back into the equation and solve
(1/x) + 2 = 0.1666
(1/x) = 0.16667 -
(1/x) = -1.8333
x = 1/(-1.83333
x ≈ -0.5455

So, the solutions to the equations are
x = 4, x = 3.6, x ≈ -0.5455
