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. Write a system of equations that can be used to find the number of white marbles, x, and the number of red marbles, y. Select one: a. x+y=15 y=6x+3 b. x+y=15 y=6x-3 c. x-y=15 y=6x+3 d. 6x+y=15 y=6x=3

    If you take the part, three more than six times the number, and break it down you can find the answer easier. 3 more is addition. Six times the number is 6*x. So you end up with adding 3 to 6x or 3+6x. Then you subtract that amount from the beginning amount because it says there are 15 marbles total and there are more red than white.
