Solution for 2(7-4(1-n))+7n=-4+2(6(n+1)-3n) equation:


Simplifying
2(7 + -4(1 + -1n)) + 7n = -4 + 2(6(n + 1) + -3n)
2(7 + (1 * -4 + -1n * -4)) + 7n = -4 + 2(6(n + 1) + -3n)
2(7 + (-4 + 4n)) + 7n = -4 + 2(6(n + 1) + -3n)

Combine like terms: 7 + -4 = 3
2(3 + 4n) + 7n = -4 + 2(6(n + 1) + -3n)
(3 * 2 + 4n * 2) + 7n = -4 + 2(6(n + 1) + -3n)
(6 + 8n) + 7n = -4 + 2(6(n + 1) + -3n)

Combine like terms: 8n + 7n = 15n
6 + 15n = -4 + 2(6(n + 1) + -3n)

Reorder the terms:
6 + 15n = -4 + 2(6(1 + n) + -3n)
6 + 15n = -4 + 2((1 * 6 + n * 6) + -3n)
6 + 15n = -4 + 2((6 + 6n) + -3n)

Combine like terms: 6n + -3n = 3n
6 + 15n = -4 + 2(6 + 3n)
6 + 15n = -4 + (6 * 2 + 3n * 2)
6 + 15n = -4 + (12 + 6n)
