A number, y, is equal to twice the sum of a smaller number and 3. The larger number is also equal to 5 more than 3 times the smaller number. Which equations represent the situation?
2 x minus y = negative 6 and 3 x minus y = negative 5
2 x minus y = negative 3 and 3 x minus y = negative 5
2 x minus y = negative 6 and x minus 3 y = 5
2 x minus y = negative 3 and x minus 3 y = 5
