To answer this item, we let x, y, and z be the prices of the properties that Michael inherited. From the given conditions in this item, we will be able to generate three equations.
x + y + z = 370000
x = y + z - 70000 2x + 3y + z = 760000
Solving for the values of the variables in this system will give us answers of: x = 150,000
y = 120,000
z = 100,000
