Answer:
16 comets
Step-by-step explanation:
This is like a simple versions of systems of equations.
You'd want to create 2 equations describing the two pieces of information they give you. First, define the variables:
# of Fantails = f
# of Comets = c
You know Gloria has 22 total, so f + c = 22
You also know there are 10 fewer f than c, so c - 10 = f
In this case, you can substitute "f" in and solve for c.
(c - 10) + c = 22
2c - 10 = 22
2c = 32
c = 16
I hoped this helped!
