Answer:
28 polio vaccinations and 32 measles vacinnacions.
Step-by-step explanation:
x= polio vaccinations
y= measles vaccinations
here we have an ecuation system:
x+y=60 (vaccinations)
2x+4y=184 (doses)
In order to solve it I will solve the x in the first ecuation:
x=60-y
And replace it on the other ecuation:
2(60-y)+4y=184 -----> 120-2y+4y=184------>2y=64------->y=32
Now I replace this result in x=60-y, so x=28.
