Solution for 4(a+4)-(4+3a)=7a-(3+6a) equation:


Simplifying
4(a + 4) + -1(4 + 3a) = 7a + -1(3 + 6a)

Reorder the terms:
4(4 + a) + -1(4 + 3a) = 7a + -1(3 + 6a)
(4 * 4 + a * 4) + -1(4 + 3a) = 7a + -1(3 + 6a)
(16 + 4a) + -1(4 + 3a) = 7a + -1(3 + 6a)
16 + 4a + (4 * -1 + 3a * -1) = 7a + -1(3 + 6a)
16 + 4a + (-4 + -3a) = 7a + -1(3 + 6a)

Reorder the terms:
16 + -4 + 4a + -3a = 7a + -1(3 + 6a)
