3.3-n=3(n-1.7)

Solution for 3.3-n=3(n-1.7) equation:

Simplifying
3.3 + -1n = 3(n + -1.7)

Reorder the terms:
3.3 + -1n = 3(-1.7 + n)
3.3 + -1n = (-1.7 * 3 + n * 3)
3.3 + -1n = (-5.1 + 3n)

Solving
3.3 + -1n = -5.1 + 3n

Solving for variable 'n'.

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

Add '-3n' to each side of the equation.
3.3 + -1n + -3n = -5.1 + 3n + -3n

Combine like terms: -1n + -3n = -4n
3.3 + -4n = -5.1 + 3n + -3n

Combine like terms: 3n + -3n = 0
3.3 + -4n = -5.1 + 0
3.3 + -4n = -5.1

Add '-3.3' to each side of the equation.
3.3 + -3.3 + -4n = -5.1 + -3.3

Combine like terms: 3.3 + -3.3 = 0.0
0.0 + -4n = -5.1 + -3.3
-4n = -5.1 + -3.3

Combine like terms: -5.1 + -3.3 = -8.4
-4n = -8.4

Divide each side by '-4'.
n = 2.1

Simplifying
n = 2.1
