Verified Answer :

 the number of white marbles, x, and the number of red marbles, y

Dylan has 15 marbles. Some are red and some are white

The number of red marbles is three more than six times the number of the white marbles

x + y = 15
y = 6x + 3

Answer:

W + R = 15 and R = 6w + 3

Step-by-step explanation:

Let Dylan has red marbles = R and number of white marbles = W

Now we will form the equation.

"Dylan has total number of marbles = 15"

R + W = 15 ----------------(1)

"Number of red marbles is three more than 6 times the number of white marbles."

R = 6w + 3 -------------(2)

Therefore, system of equations will be

W + R = 15

and R = 6w + 3
