2[3-(6-5a)]-a=-12+3(2+3a)

Solution for 2[3-(6-5a)]-a=-12+3(2+3a) equation:

Simplifying
2[3 + -1(6 + -5a)] + -1a = -12 + 3(2 + 3a)
2[3 + (6 * -1 + -5a * -1)] + -1a = -12 + 3(2 + 3a)
2[3 + (-6 + 5a)] + -1a = -12 + 3(2 + 3a)

Combine like terms: 3 + -6 = -3
2[-3 + 5a] + -1a = -12 + 3(2 + 3a)
[-3 * 2 + 5a * 2] + -1a = -12 + 3(2 + 3a)
[-6 + 10a] + -1a = -12 + 3(2 + 3a)

Combine like terms: 10a + -1a = 9a
-6 + 9a = -12 + 3(2 + 3a)
-6 + 9a = -12 + (2 * 3 + 3a * 3)
-6 + 9a = -12 + (6 + 9a)

Combine like terms: -12 + 6 = -6
-6 + 9a = -6 + 9a

Add '6' to each side of the equation.
-6 + 6 + 9a = -6 + 6 + 9a

Combine like terms: -6 + 6 = 0
0 + 9a = -6 + 6 + 9a
9a = -6 + 6 + 9a

Combine like terms: -6 + 6 = 0
9a = 0 + 9a
9a = 9a

Add '-9a' to each side of the equation.
9a + -9a = 9a + -9a

Combine like terms: 9a + -9a = 0
0 = 9a + -9a

Combine like terms: 9a + -9a = 0
0 = 0
