Answer:
Step-by-step explanation:
Let f represent the weight of Luisa’s dog.
Fabiola’s dog is 5 pounds heavier than one-third of the weight of Luisa’s dog.
Luisa' dog weight: x pounds
One-third of the weight of Luisa’s dog: pounds
5 pounds heavier than one-third of the weight of Luisa’s dog: pounds
Fabiola's dos weight: pounds that is 23 pounds.
Hence,
Solve it:
add d to both sides
c(a+b) = f + d
divide away c
a+b = (f+d)/c
subtract b from both sides:
a=[(f+d)/c]-b
