3 + -6 * 2in2s * A = 0

Multiply -6 * 2
3 + -12in2s * A = 0

Multiply in2s * A
3 + -12in2sA = 0

Solving
3 + -12in2sA = 0

Solving for variable 'i'.

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

Add '-3' to each side of the equation.
3 + -3 + -12in2sA = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -12in2sA = 0 + -3
-12in2sA = 0 + -3

Combine like terms: 0 + -3 = -3
-12in2sA = -3

Divide each side by '-12n2sA'.
i = 0.25n-2s-1A-1

Simplifying
i = 0.25n-2s-1A-1
