3.6=0.72(n+6)

Solution for 3.6=0.72(n+6) equation:

Simplifying
3.6 = 0.72(n + 6)

Reorder the terms:
3.6 = 0.72(6 + n)
3.6 = (6 * 0.72 + n * 0.72)
3.6 = (4.32 + 0.72n)

Solving
3.6 = 4.32 + 0.72n

Solving for variable 'n'.

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

Add '-0.72n' to each side of the equation.
3.6 + -0.72n = 4.32 + 0.72n + -0.72n

Combine like terms: 0.72n + -0.72n = 0.00
3.6 + -0.72n = 4.32 + 0.00
3.6 + -0.72n = 4.32

Add '-3.6' to each side of the equation.
3.6 + -3.6 + -0.72n = 4.32 + -3.6

Combine like terms: 3.6 + -3.6 = 0.0
0.0 + -0.72n = 4.32 + -3.6
-0.72n = 4.32 + -3.6

Combine like terms: 4.32 + -3.6 = 0.72
-0.72n = 0.72

Divide each side by '-0.72'.
n = -1

Simplifying
n = -1
