A bag contains blue marbles and red marbles, 106 in total. The number of blue marbles is 6 more than 4 times the number of red marbles. How many blue marbles are there?

Number of blue marbles = 86.

Step-by-step explanation:

Let number of blue marbles = x, then the number of red marbles = 106-x.

From the second relation given in the question:-

x = 4 (106 - x) + 6

Solving for x:-

x = 424 - 4x + 6

5x = 430

x = 86 blue marbles.
