0=2*(n-1)+1

Solution for 0=2*(n-1)+1 equation:

Simplifying
0 = 2(n + -1) + 1

Reorder the terms:
0 = 2(-1 + n) + 1
0 = (-1 * 2 + n * 2) + 1
0 = (-2 + 2n) + 1

Reorder the terms:
0 = -2 + 1 + 2n

Combine like terms: -2 + 1 = -1
0 = -1 + 2n

Solving
0 = -1 + 2n

Solving for variable 'n'.

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

Add '-2n' to each side of the equation.
0 + -2n = -1 + 2n + -2n
Remove the zero:
-2n = -1 + 2n + -2n

Combine like terms: 2n + -2n = 0
-2n = -1 + 0
-2n = -1

Divide each side by '-2'.
n = 0.5

Simplifying
