-7nI + 2nxI = (7 * nI + -1x * nI)
-7nI + 2nxI = (7nI + -1nxI)

Solving
-7nI + 2nxI = 7nI + -1nxI

Solving for variable 'n'.

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

Add '-7nI' to each side of the equation.
-7nI + -7nI + 2nxI = 7nI + -7nI + -1nxI

Combine like terms: -7nI + -7nI = -14nI
-14nI + 2nxI = 7nI + -7nI + -1nxI

Combine like terms: 7nI + -7nI = 0
-14nI + 2nxI = 0 + -1nxI
-14nI + 2nxI = -1nxI

Add 'nxI' to each side of the equation.
-14nI + 2nxI + nxI = -1nxI + nxI

Combine like terms: 2nxI + nxI = 3nxI
-14nI + 3nxI = -1nxI + nxI
