The height of the first building is 23 feet more than three times the height of the second building. If the difference in their heights is 415.5 ​feet, find the heights of the two buildings.

Question

what is the height of the first building in feet and the height of the second building in feet ?

Answer 1

f = 3s + 23

f - s = 415.5

We can substitute either side of the = because they are "the same."

3s + 23 - s = 415.5

2s = 392.5

s = 196.25 ft

f = 3(196.25) + 23 = your 2nd answer
