There are 15 plates in a kitchen cabinet. The diameter of each plate is either 7 inches or 12 inches. The diameter of all 15 plates combined is 140 inches.

Which system of equations can be used to find the number of 7 inch plates, x, and the number of 12 inch plates, y, that are in the cabinet?

• x + y = 140

  12x +7y = 15

• 7x +12y = 140

  7x +12y = 15

• x + y = 15

  7x +12y = 140

• x + y = 15

  12x +7y = 140
