City A and City B had two different temperatures on a particular day. On that day, four times the temperature of City A was 8° C more than three times the temperature of Cīty B. The temperature of City A minus twice the temperature of City B was -3° C. The following system of equations models this scenario. 4x = 8 + 3y
x - 2y = -3
What was the temperature of City A and City B on that day?
