Hiroto solved the equation 6 – 4|2x – 8| = –10 for one solution. His work is shown below.6 – 4|2x – 8| = –10 –4|2x – 8| = –16|2x – 8| = 42x – 8 = 42x = 12 x = 6

Add 4|2x − 8| to both sides and add 10 to both sides to get |2x − 8| = 4. Hiroto used 2x − 8 = 4, which gives x = 6; the other possibility is 2x − 8 = −4, giving x = 2. So the other solution is 2, choice C.
