The sum of two numbers is 11. The bigger number is one less than three time the smaller number. Determine which of the following answer has the System of Equation we would use to solve the Given Problem with the correct answer.
Let x = the smaller number
y=the bigger number

A)x+y = 11x = 3y - 1 x = 6y = -17
B)x-y= 11 y = 3x - 1 x = 6 y = 17
C)x+y = 11 y = 3x - 1 x = 3 y = 8
D)x+y = 11 x = 3y - 1 x = 8 y = 3
