Solution for 4(a+3)=10[a-(7-a)] equation:


Simplifying
4(a + 3) = 10[a + -1(7 + -1a)]

Reorder the terms:
4(3 + a) = 10[a + -1(7 + -1a)]
(3 * 4 + a * 4) = 10[a + -1(7 + -1a)]
(12 + 4a) = 10[a + -1(7 + -1a)]
12 + 4a = 10[a + (7 * -1 + -1a * -1)]
12 + 4a = 10[a + (-7 + 1a)]

Reorder the terms:
12 + 4a = 10[-7 + a + 1a]

Combine like terms: a + 1a = 2a
12 + 4a = 10[-7 + 2a]
12 + 4a = [-7 * 10 + 2a * 10]
12 + 4a = [-70 + 20a]
