    Answer: The equations that can be used to find the number of 7 inch plates, x, and the number of 12 inch plate, y, that are in the cabinet are

    x + y = 15

    7x + 12y = 140

    Step-by-step explanation:

    The diameter of each plate is either 7 inches or 12 inches.

    Let x represent the number of 7 inches plate

    Let y represent the number of 12 inches plate

    There are 15 plates in the kitchen cabinet. This means that the sum of the 7 inches plate and the 12 inches plate is 15. It is expressed as

    x + y = 15

    The diameter of all 15 plates combined is 140 inches. This means that

    7x + 12y = 140
