By dividing the number of houses in antonio's subdivision by 4 and adding 15, you can find the number of houses in hector's subdivision. if hector has 47 houses in his subdivision, how many houses are in antonio's subdivision?
let x--------> the number of houses in antonio's subdivision y-------> the number of houses in hector's subdivision
we know that (x/4)+15=y----> equation 1 y=47-----> equation 2
substitute equation 2 in equation 1 (x/4)+15=47-----> multiply by 4----> x+60=188-----> x=128 the answer is the number of houses in antonio's subdivision are 128
