Solution for 3(6-n)+4(3n+5)+3(6-n)=4(3+n) equation:


Simplifying
3(6 + -1n) + 4(3n + 5) + 3(6 + -1n) = 4(3 + n)
(6 * 3 + -1n * 3) + 4(3n + 5) + 3(6 + -1n) = 4(3 + n)
(18 + -3n) + 4(3n + 5) + 3(6 + -1n) = 4(3 + n)

Reorder the terms:
18 + -3n + 4(5 + 3n) + 3(6 + -1n) = 4(3 + n)
18 + -3n + (5 * 4 + 3n * 4) + 3(6 + -1n) = 4(3 + n)
18 + -3n + (20 + 12n) + 3(6 + -1n) = 4(3 + n)
18 + -3n + 20 + 12n + (6 * 3 + -1n * 3) = 4(3 + n)
18 + -3n + 20 + 12n + (18 + -3n) = 4(3 + n)

Reorder the terms:
18 + 20 + 18 + -3n + 12n + -3n = 4(3 + n)

Combine like terms: 18 + 20 = 38
38 + 18 + -3n + 12n + -3n = 4(3 + n)

Combine like terms: 38 + 18 = 56
56 + -3n + 12n + -3n = 4(3 + n)

Combine like terms: -3n + 12n = 9n
56 + 9n + -3n = 4(3 + n)

Combine like terms: 9n + -3n = 6n
56 + 6n = 4(3 + n)
56 + 6n = (3 * 4 + n * 4)
56 + 6n = (12 + 4n)

Solving
56 + 6n = 12 + 4n

Solving for variable 'n'.
