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
