Answer:
The total number of Cats and Frogs
Step-by-step explanation:
Number of Birds Owned = B
Number of Cats = C
Number of Frogs =F
The expression that represents the total number of pets owned by Kelby
=B+(C+F)
NOTE: SUM/ADDITION = +
Therefore:
The expression C+F represents the total number of Cats and Frogs owned by Kelby.
Answer:
Step-by-step explanation:
Solve the system:
8x−4y=20
4x−8y=4
Reduce the first equation by dividing every term by -2:
-4x + 2y = -10
and then combine this result with the second equation:
4x−8y=4
-4x + 2y = -10
--------------------
-6y = -6, and so y = 1.
According to the first equation, if y = 1, then 4x - 8 = 4, or x = 3.
Then x = 3 and y = 1.
So, finally, x - y = 3 - 1 = 2
then find y and plug that y value into one of the original equations to find x
Hope this helps!
