How to solve this one

Answer:
Simon has 24 more monies than Ali
Step-by-step explanation:
Simon and Ali start of with the same amount of money. Let's say 50!
S=50
A=50
Simon gives Ali 12 of his monies so we subtract 12 from Simon and add 12 to Ali.
S=50-12
A=50+12
Simon now has 38 monies
Ali now has 62 monies
62-38=24!
Hope this helps!
