Finding Savings Equality

Jasmine and Liam are each saving money to buy a new laptop. Jasmine starts with $200 and saves $50 per month. Liam starts with $150 and saves $75 per month.

Let x represent the number of months after they start saving. Write a system of equations to represent the amount of money each person has saved after x months. Then, determine after how many months their savings will be equal.
