Answer:
36 blue Candies
Step-by-step explanation:
Let
x ----> the number of blue Candies
y ----> the number of yellow Candies
we know that
The ratio of blue candied and yellow candies is 3:5
so
----> equation A
the bag contains 60 yellow Candies
so
----> equation B
substitute equation B in equation A
solve for x
Actually Welcome to the concept of logarithms.
Since here the log is on both sides, we take antilog on both sides, so we get as,
==> 2-x = -5x - 18
==> -x + 5x = -18 -2
==> 4x = -20
==> x = -20/4
==> x = -5
hence, x = -5
