-3-(n-1)-2(n-2)=-3+(n-2)+4

Solution for -3-(n-1)-2(n-2)=-3+(n-2)+4 equation:

Simplifying
-3 + -1(n + -1) + -2(n + -2) = -3 + (n + -2) + 4

Reorder the terms:
-3 + -1(-1 + n) + -2(n + -2) = -3 + (n + -2) + 4
-3 + (-1 * -1 + n * -1) + -2(n + -2) = -3 + (n + -2) + 4
-3 + (1 + -1n) + -2(n + -2) = -3 + (n + -2) + 4

Reorder the terms:
-3 + 1 + -1n + -2(-2 + n) = -3 + (n + -2) + 4
-3 + 1 + -1n + (-2 * -2 + n * -2) = -3 + (n + -2) + 4
-3 + 1 + -1n + (4 + -2n) = -3 + (n + -2) + 4

Reorder the terms:
-3 + 1 + 4 + -1n + -2n = -3 + (n + -2) + 4

Combine like terms: -3 + 1 = -2
-2 + 4 + -1n + -2n = -3 + (n + -2) + 4

Combine like terms: -2 + 4 = 2
2 + -1n + -2n = -3 + (n + -2) + 4

Combine like terms: -1n + -2n = -3n
2 + -3n = -3 + (n + -2) + 4

Reorder the terms:
2 + -3n = -3 + (-2 + n) + 4

Remove parenthesis around (-2 + n)
2 + -3n = -3 + -2 + n + 4

Reorder the terms:
2 + -3n = -3 + -2 + 4 + n

Combine like terms: -3 + -2 = -5
2 + -3n = -5 + 4 + n

Combine like terms: -5 + 4 = -1
2 + -3n = -1 + n

Solving
2 + -3n = -1 + n

Solving for variable 'n'.

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

Add '-1n' to each side of the equation.
2 + -3n + -1n = -1 + n + -1n

Combine like terms: -3n + -1n = -4n
2 + -4n = -1 + n + -1n

Combine like terms: n + -1n = 0
2 + -4n = -1 + 0
2 + -4n = -1

Add '-2' to each side of the equation.
2 + -2 + -4n = -1 + -2

Combine like terms: 2 + -2 = 0
0 + -4n = -1 + -2
-4n = -1 + -2

Combine like terms: -1 + -2 = -3
-4n = -3

Divide each side by '-4'.
n = 0.75

Simplifying
n = 0.75
