Question

Translate in to Algebraic equation. I had some money and I gave away $20 the first day, gained 3 times my original amount on the second day, and noticed that I now have $80.

Answer 1

Let x represent the amount of money you originally had. The algebraic expression would be: x-20+3×=80.
If you want to solve the equation, it would be: 4x=100, and x=100÷4, which equals 25. So your original money was $25.
