Solve by splitting the absolute value into two cases (since 18 ≥ 0):
x + 3 = 18 => x = 15
x + 3 = −18 => x = −21
Check: |15 + 3| = |18| = 18 and |−21 + 3| = |−18| = 18. So the solutions are x = 15 and x = −21.
x + 3 = 18 => x = 15
x + 3 = −18 => x = −21
Check: |15 + 3| = |18| = 18 and |−21 + 3| = |−18| = 18. So the solutions are x = 15 and x = −21.
