A bag contains white marbles and blue marbles, 41 in total.

Question

The number of white marbles is 6 more than 4 times the number of blue marbles. How many white marbles are there?

Answer 1

Let x = the number of blue marbles

Let 4x + 6 = the number of white marbles

4x + 6 + x = 41

5x = 35

x = 7 blue marbles

4x + 6 = 4(7) + 6 = 28 + 6 = 34 white marbles
