1.2=x-sin(x)

Solution for 1.2=x-sin(x) equation:

Simplifying
1.2 = x + -1sin(x)

Multiply ins * x
1.2 = x + -1insx

Reorder the terms:
1.2 = -1insx + x

Solving
1.2 = -1insx + x

Solving for variable 'i'.

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

Add 'insx' to each side of the equation.
1.2 + insx = -1insx + insx + x

Combine like terms: -1insx + insx = 0
1.2 + insx = 0 + x
1.2 + insx = x

Add '-1.2' to each side of the equation.
1.2 + -1.2 + insx = -1.2 + x

Combine like terms: 1.2 + -1.2 = 0.0
0.0 + insx = -1.2 + x
insx = -1.2 + x

Divide each side by 'nsx'.
i = -1.2n-1s-1x-1 + n-1s-1

Simplifying
i = -1.2n-1s-1x-1 + n-1s-1

Reorder the terms:
i = n-1s-1 + -1.2n-1s-1x-1
