-(n-1)=-2(n+3)

Solution for -(n-1)=-2(n+3) equation:

Simplifying
-1(n + -1) = -2(n + 3)

Reorder the terms:
-1(-1 + n) = -2(n + 3)
(-1 * -1 + n * -1) = -2(n + 3)
(1 + -1n) = -2(n + 3)

Reorder the terms:
1 + -1n = -2(3 + n)
1 + -1n = (3 * -2 + n * -2)
1 + -1n = (-6 + -2n)

Solving
1 + -1n = -6 + -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.
1 + -1n + 2n = -6 + -2n + 2n

Combine like terms: -1n + 2n = 1n
1 + 1n = -6 + -2n + 2n

Combine like terms: -2n + 2n = 0
1 + 1n = -6 + 0
1 + 1n = -6

Add '-1' to each side of the equation.
1 + -1 + 1n = -6 + -1

Combine like terms: 1 + -1 = 0
0 + 1n = -6 + -1
1n = -6 + -1

Combine like terms: -6 + -1 = -7
1n = -7

Divide each side by '1'.
n = -7

Simplifying
n = -7
