Answer:
x=3
Step-by-step explanation:
since they give you y this is a very simple problem
simply replace y with -3 and get

adding a negative number is the same as subtracting a positive number
3x-3=6
add 3 on both sides
3x=9
divide by 3 on both sides
x=3

Answer:
21
Step-by-step explanation:
21/3 = 7
Using the proportion given, there will be 57 catfish in the pond.
The proportion given to us is
5.7/20 = x/200
Cross multiply:
5.7*200 = 20*x
1140 = 20x
Divide both sides by 20:
1140/20 = 20x/20
57 = x
