Today’s Bandit Error
Catch the shortcut before it catches you.
Bandit took the 5 off one side and left the other side alone. Can you catch it in five seconds?
Bandit wrote:
Fast route: clear the 5 off the left and leave the 12 alone. But an equation is a balance — whatever comes off one side has to come off the other.
✗x + 5 = 12, so x = 12
✓x + 5 − 5 = 12 − 5, so x = 7
