Distribute 2 to all terms within the parenthesis.
2(8x - 4) = 16x - 8
Simplify. Combine like terms
16x - 8 - 2x = 14x - 8
14x - 8 ≤ 14x + 12
Isolate the x. Subtract 14x from both sides, and add 8 to both sides
14x (-14x) - 8 (+8) ≤ 14x (-14x) + 12 (+8)
14x - 14x ≤ 12 + 8
Simplify
0 ≤ 20 (True)
True is your answer
