Solve .
Hint
The two equations for the solutions are .
Answer
x = 27 or -27
Solve |x – 11| = 2.
The two equations for the solutions are x – 11 = ±2.
x = 13 or 9
Solve |4x + 9 + 21x| = 81.
The two equations for the solutions are 25x + 9 = ±81.
Solve |3(x + 2)| = 15.
The two equations for the solutions are 3x + 6 = ±15.
x = 3 or -7
Solve 3 + |13 – x| = 21.
Get the absolute value by itself, then solve. The two equations for the solutions are 13 – x = ±18.
x = -5 or 31
