Let
x---------> the number of blue cubes
y--------> the number of red cubes
we know that

so
solve for y
I proceed to calculate a table, assuming values of x to calculate the value of y. When the values of x and y are whole numbers, I will have found the solution.
the table in the attached figure
therefore
