Let the age of devaughn be x and Sydney be y.
Then,x+y=45
x+5=y
y=x+5
here,
put y=x+y in x+y=45
then,
x+y=45
x+x+5=45
2x=40
x=20
now,
y=x+5
y=20+5
y=25

Answer:
dogs = 79
dats = 90
fish = 183
Step-by-step explanation:
let the total number of dogs owned be x
no. of cats owned = x+11
no. of fish owned = x+11+x+14= 2x+25
hence,
2x+25+x+11+x=352
4x=316
x=316/4= 79mil
no. of cats owned = 79 + 11 = 90
no. of fish owned = 2(79)+25=183
