0 = 0
The equation is an identity, all real numbers are solutions.
Step-by-step explanation:
First we simplify:
4[24 + - 3 (7x + 6) ] + - 6 (4 + - 14x) = 0
Then we need to reorder the terms:
=> 4[24 + - 3 (6 + 7x) ] + - 6 (4 + - 14x) = 0
=> 4[24 + (6 * - 3 + 7x * - 3) ] + - 6 (4 + - 14x) = 0
=> 4[24 + (-18 + - 21x) ] + - 6 (4 + - 14x) = 0
We the have to combine like terms:
24 + - 18 = 6
=> 4[6 + - 21x] + - 6 (4 + - 14x) = 0
=> [6 * 4 + - 21x * 4] + - 6 (4 + - 14x) = 0
=> [24 + - 84x] + - 6 (4 + - 14x) = 0
=> 24 + - 84x + (4 * - 6 + - 14x * - 6) = 0
=> 24 + - 84x + (-24 + 84x) = 0
Reorder the terms again:
24 + - 24 + - 84x + 84x = 0
Combine like terms again:
24 + - 24 = 0
=> 0 + - 84x + 84x = 0
=> - 84x + 84x = 0
Then once again, combine like terms:
-84x + 84x = 0
=> 0 = 0
