Building A is 150 feet shorter than Building B. The height of both building is 1530 feet. Find the height of both building A and B.

Let a be the height of building A
Let b be the height of building B

We're given two equations:

1. a = b - 150
2. a + b = 1530

To solve this system of equations, we substitute equation (1) into equation (2) for a:
(b - 150) + b = 1530

To solve this equation for b, we type it in our search engine and we get:
b = 840

To solve for a, we substitute b = 840 into equation (1):
a = 840 - 150
a = 690
