n+2N+(n+10)=4.50

Solution for n+2N+(n+10)=4.50 equation:

Simplifying
n + 2N + (n + 10) = 4.50

Reorder the terms:
n + 2N + (10 + n) = 4.50

Remove parenthesis around (10 + n)
n + 2N + 10 + n = 4.50

Reorder the terms:
10 + 2N + n + n = 4.50

Combine like terms: n + n = 2n
10 + 2N + 2n = 4.50

Solving
10 + 2N + 2n = 4.50

Solving for variable 'N'.

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

Add '-10' to each side of the equation.
10 + 2N + -10 + 2n = 4.50 + -10

Reorder the terms:
10 + -10 + 2N + 2n = 4.50 + -10

Combine like terms: 10 + -10 = 0
0 + 2N + 2n = 4.50 + -10
2N + 2n = 4.50 + -10

Combine like terms: 4.50 + -10 = -5.5
2N + 2n = -5.5

Add '-2n' to each side of the equation.
2N + 2n + -2n = -5.5 + -2n

Combine like terms: 2n + -2n = 0
2N + 0 = -5.5 + -2n
2N = -5.5 + -2n

Divide each side by '2'.
N = -2.75 + -1n

Simplifying
N = -2.75 + -1n
