Solution for 5(2n+4)-3(4n-6)=2(20-n) equation:


Simplifying
5(2n + 4) + -3(4n + -6) = 2(20 + -1n)

Reorder the terms:
5(4 + 2n) + -3(4n + -6) = 2(20 + -1n)
(4 * 5 + 2n * 5) + -3(4n + -6) = 2(20 + -1n)
(20 + 10n) + -3(4n + -6) = 2(20 + -1n)

Reorder the terms:
20 + 10n + -3(-6 + 4n) = 2(20 + -1n)
20 + 10n + (-6 * -3 + 4n * -3) = 2(20 + -1n)
20 + 10n + (18 + -12n) = 2(20 + -1n)

Reorder the terms:
20 + 18 + 10n + -12n = 2(20 + -1n)

Combine like terms: 20 + 18 = 38
38 + 10n + -12n = 2(20 + -1n)

Combine like terms: 10n + -12n = -2n
38 + -2n = 2(20 + -1n)
38 + -2n = (20 * 2 + -1n * 2)
38 + -2n = (40 + -2n)

Add '2n' to each side of the equation.
38 + -2n + 2n = 40 + -2n + 2n

Combine like terms: -2n + 2n = 0
38 + 0 = 40 + -2n + 2n
38 = 40 + -2n + 2n

Combine like terms: -2n + 2n = 0
38 = 40 + 0
38 = 40
