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 windows. Altogether, 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.(1 point)
Let's assume the number of office buildings is x.
The number of windows in the office buildings = 21x
The total number of windows = number of windows in the office buildings + number of windows in the school = 21x + 42
According to the problem, the total number of windows is 126.
Therefore, the equation that would be used to solve this problem algebraically is 21x + 42 = 126.
Let's assume the number of office buildings is represented by 'x'.
The number of windows cleaned per office building is given as 21.
Therefore, the total number of windows cleaned in all office buildings is (21 * x).
The number of windows cleaned in the school is given as 42.
The total number of windows cleaned in all buildings and school is given as 126.
So, the equation to solve this algebraically is (21 * x) + 42 = 126.
To solve this problem algebraically, let's assume the number of office buildings is "x".
Given that a window cleaner can clean 21 windows per office building, the number of windows cleaned in the office buildings would be 21 * x.
The number of windows cleaned in the school with 42 windows is simply 42.
So, the total number of windows cleaned would be 21x + 42.
According to the problem, the total number of windows cleaned is 126. Therefore, we can set up the equation:
21x + 42 = 126
Now, to find the number of office buildings, we can solve this equation.
