Solving for variable 'i'.

Move all terms containing i to the left, all other terms to the right.

Add '-0.5insx' to each side of the equation.
3 + -0.5insx = 0.5insx + -0.5insx

Combine like terms: 0.5insx + -0.5insx = 0.0
3 + -0.5insx = 0.0

Add '-3' to each side of the equation.
3 + -3 + -0.5insx = 0.0 + -3

Combine like terms: 3 + -3 = 0
0 + -0.5insx = 0.0 + -3
-0.5insx = 0.0 + -3

Combine like terms: 0.0 + -3 = -3
-0.5insx = -3

Divide each side by '-0.5nsx'.
i = 6n-1s-1x-1

Simplifying
i = 6n-1s-1x-1
