Stacia wanted concert tickets that were selling for $36 each, and then she got a $19 discount. She paid a total of $53 for the tickets. How many tickets did she buy? Identify the operations needed to solve this problem using the equation 36x −19=53
To solve the equation 36x - 19 = 53, we need to isolate the variable, x, which represents the number of tickets Stacia bought.
To isolate x, we'll perform the following operations:
1. Add 19 to both sides of the equation: 36x - 19 + 19 = 53 + 19
This simplifies to: 36x = 72
2. Divide both sides of the equation by 36: 36x/36 = 72/36
This simplifies to: x = 2
Therefore, Stacia bought 2 tickets.

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.
To solve the problem algebraically, let's denote the number of office buildings as "x".
According to the given information, the window cleaner can clean 21 windows per office building. Therefore, the number of windows cleaned in the office buildings is 21x.
Additionally, the window cleaner can clean 42 windows at the school.
The total number of windows cleaned is given as 126. So, we can create the equation:
21x + 42 = 126
This is the equation that would be used to solve the problem algebraically.
