Solution for 7(a+2)=6[a-(1-a)] equation:


Simplifying
7(a + 2) = 6[a + -1(1 + -1a)]

Reorder the terms:
7(2 + a) = 6[a + -1(1 + -1a)]
(2 * 7 + a * 7) = 6[a + -1(1 + -1a)]
(14 + 7a) = 6[a + -1(1 + -1a)]
14 + 7a = 6[a + (1 * -1 + -1a * -1)]
14 + 7a = 6[a + (-1 + 1a)]

Reorder the terms:
14 + 7a = 6[-1 + a + 1a]

Combine like terms: a + 1a = 2a
14 + 7a = 6[-1 + 2a]
14 + 7a = [-1 * 6 + 2a * 6]
14 + 7a = [-6 + 12a]

Solving
14 + 7a = -6 + 12a
