Question

A bag contains purple marbles and red marbles, 34 in total. The number of purple marbles is 8 less than 5 times the number of red marbles. How many purple marbles are there?

Answer 1

p = 27

r = 7

Explanation:

p + r = 34

5r - 8 = p => 5r - p = 8

Add both => 6r = 34 + 8 = 42 => r =7

p= 34 - r => p = 27
