The number of the blue marbles are in the box will be 102.

<h3>What is the solution of the equation?</h3>

The solution of the equation means the value of the unknown or variable.

A box contains 162 marbles which are either red (r) or blue (b).

r + b = 162 ...1

There are 42 more blue marbles than red marbles.

b = r + 42 ...2

Then from equation 1 and 2, we have

r + r + 42 = 162

2r = 120

r = 60

Then the number of blue marble will be

b = 60 + 42

b = 102
