Johan found that the equation –2|8 – x| – 6 = –12 had two possible solutions: x = 5 and x = –11. which explains whether his solutions are correct?

x = 5 is correct, x = - 11 is incorrect

step-by-step explanation:

to determine if the solutions obtained are correct

substitute the values into the left side of the equation and if equal to the right side then they are solutions.

testing x = 5

- 2 | 8 - 5 | - 6

= - 2 | 3 | - 6

= (- 2× 3) - 6

= - 6 - 6 = - 12 ← correct hence x = 5 is a solution

testing x = - 11

- 2 | 8 - (- 11 ) | - 6

= - 2 | 8 + 11 | - 6

= - 2 | 19 | - 6

= (- 2 × 19) - 6

= - 38 - 6 = - 44 ≠ - 12 hence x = - 11 is incorrect
