A window cleaner has enough supplies to clean 21 Windows per office building on a certain number of buildings they can also clean the windows of a school with 42 winners all together there are enough supplies to clean 126 Windows how many Office Buildings can be washed identify the equation that would be used to solve this problem algebraically
Let's assume the number of office buildings is x.
The number of windows in each office building is 21x.
The number of windows in the school is 42.
Therefore, the total number of windows to be cleaned is 21x + 42.
We know that the total number of windows that can be cleaned is 126, so we can write the equation as follows:
21x + 42 = 126
