c represents cost of the first house
c + 6000 represents the cost of the second
c + 6000 + 4000 represents the cost of the third
c + c + 6000 + c + 6000 + 4000 = 44000 combine like terms
3c + 16000 = 44000 subtract 14000 from both sides
3c = 28000 divide both sides by 3
c = 9333.33
The first house cost $9,333.33
Can you find the cost of the other two?
