n-1.6n+2.2=-4(n+5.4)

Solution for n-1.6n+2.2=-4(n+5.4) equation:

Simplifying
n + -1.6n + 2.2 = -4(n + 5.4)

Reorder the terms:
2.2 + n + -1.6n = -4(n + 5.4)

Combine like terms: n + -1.6n = -0.6n
2.2 + -0.6n = -4(n + 5.4)

Reorder the terms:
2.2 + -0.6n = -4(5.4 + n)
2.2 + -0.6n = (5.4 * -4 + n * -4)
2.2 + -0.6n = (-21.6 + -4n)

Solving
2.2 + -0.6n = -21.6 + -4n

Solving for variable 'n'.

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

Add '4n' to each side of the equation.
2.2 + -0.6n + 4n = -21.6 + -4n + 4n

Combine like terms: -0.6n + 4n = 3.4n
2.2 + 3.4n = -21.6 + -4n + 4n

Combine like terms: -4n + 4n = 0
2.2 + 3.4n = -21.6 + 0
2.2 + 3.4n = -21.6

Add '-2.2' to each side of the equation.
2.2 + -2.2 + 3.4n = -21.6 + -2.2

Combine like terms: 2.2 + -2.2 = 0.0
0.0 + 3.4n = -21.6 + -2.2
3.4n = -21.6 + -2.2

Combine like terms: -21.6 + -2.2 = -23.8
3.4n = -23.8

Divide each side by '3.4'.
n = -7

Simplifying
n = -7
