Q. Solve the equation.\newline∣x∣=4 |x|=4
  1. Understand absolute value equation: The absolute value of xx is the distance from zero on the number line, which doesn't consider direction.
  2. Write possible solutions: Write the possible solutions for xx.\newlineSince ∣x∣=4|x| = 4, xx can be either 44 or −4-4.\newlinex=4x = 4 or x=−4x = -4
