Let B be the number of blue marbles, R red.
1.6B=2R%2B18
2.5B=6R-2
From eq. 1,
B=R%2F3%2B6
Substitute into eq. 2,
%285%2F3%29R%2B6%2F5=6R-2
Multiply both sides by 15.
25R%2B18=90R-30
65R=48
R is not an integer value which it must be.
Check the problem setup.
"three times the number twice of blue marbles"
Is this correct? Three times twice is 6 times.
