-21 + n = -1n + -1nx

Solving for variable 'n'.

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

Add 'n' to each side of the equation.
-21 + n + n = -1n + n + -1nx

Combine like terms: n + n = 2n
-21 + 2n = -1n + n + -1nx

Combine like terms: -1n + n = 0
-21 + 2n = 0 + -1nx
-21 + 2n = -1nx

Add 'nx' to each side of the equation.
-21 + 2n + nx = -1nx + nx

Combine like terms: -1nx + nx = 0
-21 + 2n + nx = 0

Add '21' to each side of the equation.
-21 + 2n + 21 + nx = 0 + 21

Reorder the terms:
-21 + 21 + 2n + nx = 0 + 21

Combine like terms: -21 + 21 = 0
0 + 2n + nx = 0 + 21
2n + nx = 0 + 21

Combine like terms: 0 + 21 = 21
2n + nx = 21

Reorder the terms:
-21 + 2n + nx = 21 + -21

Combine like terms: 21 + -21 = 0
-21 + 2n + nx = 0
