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)

42x+21=126
42 x plus 21 equals 126

21x+42=126
21 x plus 42 equals 126

21x−42=126
21 x minus 42 equals 126

42x−21=126

To solve this problem using the equation b8 + 25 = 500, we need to use addition and multiplication.

First, let's break down the equation step by step:

1. b8 + 25 = 500: This equation represents the total number of beads Neil has, starting with an unknown amount, making 8 identical necklaces, and buying 25 beads at the store.

2. To isolate the variable b (representing the number of beads Neil started with), we need to get rid of the +25 on the left side of the equation. We can do this by subtracting 25 from both sides of the equation:

b8 + 25 - 25 = 500 - 25

Simplifying, we get:

b8 = 475

3. Now that we have b8 = 475, we need to divide both sides of the equation by 8 to solve for b:

(b8)/8 = 475/8

Simplifying, we get:

b = 59.375

Since it is not possible to have a fractional number of beads, we can conclude that Neil started with 59 beads to make 8 identical necklaces.
