5 ? Writing a System of Linear Equations

Determine the system of linear equations that represent a given situation

A phone company offers two long distance plans.The first charges a flat value of $5.00 per month plus $0.99 for each minute used, and the second charges $10.00 a month plus $0.79 for each minute used.

If x represents the number of minutes used each month, which system of equations represents the total amount of money, y, you would spend for each long distance plan?
