Answer:
They say that the sum of the two numbers (x and y) is 64, so we can write our first equation by adding them and setting that sum equal to 64:
x + y = 64
The question also tells us that their difference is 14. Similarly to before, we'll just subtract the two numbers and set that difference equal to 14:
x - y = 14
Now from here, you know how to continue with substitution to find the values for x and y. Just remember when you get a word problem to break it down and look for key words like sum, difference, or product, and from there you'll be able to build your system of equations.

You would need to isolate the "X" variable because it is common in all 3 equations.
Answer: There are 48 butterflies altogether.
Step-by-step explanation:
Since we have given that
The ratio of number of pink butterflies to the number of yellow butterflies is 3:5
So,
Let the number of pink butterflies be 3x
Let the number of yellow butterflies be 5x
As we have given that there are 18 pink butterflies,
So,
So, total number of butterflies is given by
Hence, there are 48 butterflies altogether.
