2n+(2n+1.2)=4n+(2n+0.1)

Solution for 2n+(2n+1.2)=4n+(2n+0.1) equation:

Simplifying
2n + (2n + 1.2) = 4n + (2n + 0.1)

Reorder the terms:
2n + (1.2 + 2n) = 4n + (2n + 0.1)

Remove parenthesis around (1.2 + 2n)
2n + 1.2 + 2n = 4n + (2n + 0.1)

Reorder the terms:
1.2 + 2n + 2n = 4n + (2n + 0.1)

Combine like terms: 2n + 2n = 4n
1.2 + 4n = 4n + (2n + 0.1)

Reorder the terms:
1.2 + 4n = 4n + (0.1 + 2n)

Remove parenthesis around (0.1 + 2n)
1.2 + 4n = 4n + 0.1 + 2n

Reorder the terms:
1.2 + 4n = 0.1 + 4n + 2n

Combine like terms: 4n + 2n = 6n
1.2 + 4n = 0.1 + 6n

Solving
1.2 + 4n = 0.1 + 6n

Solving for variable 'n'.

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

Add '-6n' to each side of the equation.
1.2 + 4n + -6n = 0.1 + 6n + -6n

Combine like terms: 4n + -6n = -2n
1.2 + -2n = 0.1 + 6n + -6n

Combine like terms: 6n + -6n = 0
1.2 + -2n = 0.1 + 0
1.2 + -2n = 0.1

Add '-1.2' to each side of the equation.
1.2 + -1.2 + -2n = 0.1 + -1.2

Combine like terms: 1.2 + -1.2 = 0.0
0.0 + -2n = 0.1 + -1.2
-2n = 0.1 + -1.2

Combine like terms: 0.1 + -1.2 = -1.1
-2n = -1.1

Divide each side by '-2'.
n = 0.55

Simplifying
n = 0.55
