2a + -1(-6 + 4a + -2a) = 2a + -1(4a + -1[2(a + 1) + 4])

Combine like terms: 4a + -2a = 2a
2a + -1(-6 + 2a) = 2a + -1(4a + -1[2(a + 1) + 4])
2a + (-6 * -1 + 2a * -1) = 2a + -1(4a + -1[2(a + 1) + 4])
2a + (6 + -2a) = 2a + -1(4a + -1[2(a + 1) + 4])

Reorder the terms:
6 + 2a + -2a = 2a + -1(4a + -1[2(a + 1) + 4])

Combine like terms: 2a + -2a = 0
6 + 0 = 2a + -1(4a + -1[2(a + 1) + 4])
6 = 2a + -1(4a + -1[2(a + 1) + 4])

Reorder the terms:
6 = 2a + -1(4a + -1[2(1 + a) + 4])
6 = 2a + -1(4a + -1[(1 * 2 + a * 2) + 4])
6 = 2a + -1(4a + -1[(2 + 2a) + 4])

Reorder the terms:
6 = 2a + -1(4a + -1[2 + 4 + 2a])

Combine like terms: 2 + 4 = 6
6 = 2a + -1(4a + -1[6 + 2a])
6 = 2a + -1(4a + [6 * -1 + 2a * -1])
6 = 2a + -1(4a + [-6 + -2a])

Reorder the terms:
6 = 2a + -1(-6 + 4a + -2a)

Combine like terms: 4a + -2a = 2a
6 = 2a + -1(-6 + 2a)
6 = 2a + (-6 * -1 + 2a * -1)
6 = 2a + (6 + -2a)

Reorder the terms:
6 = 6 + 2a + -2a
