Question

Solve the equation. |k + 7| = 3 A. {–4, 10} B. {–10, –4} C. {–4, 4} D. {all real numbers greater than or equal to –10 and less than or equal to – 4}

Answer 1

There should be two different equations k+7=3 and k+7=-3. Then you should solve by subtracting 7 from both sides. Should get {-10,-4}
