Let
x--------> The number of red marbles
y--------> The number of blue marbles
we know that
x + y = 27 x = 27 − y
equation 1
x = 3 y − 5
equation 2
equate equation 1 and equation 2
27 − y = 3 y − 5 3 y + y = 27 + 5 4 y = 32 y = 8
x = 3 ∗ 8 − 5 x = 19
therefore
the answer is
The number of red marbles is 19
The number of blue marbles is 8
