This math problem went viral after being posted in 2020.
Celeste Ng tweeted 'At dinner, nine year old made up a math problem and made his father and me solve it. Our attempt at simultaneous equations got really complicated. We figured it out via guess and check, but I still think there has to be a more elegant way.'
Can you solve the nine year old math problem using both guess and check and the elegant way - using algebra?
