can you help ; i need to

write and solve for each situation. check the solution.

school: between 7:30am and 8:00am the number of students in a school increased by 73. there were 152 students in the school at 8:00 am. How many students were in school at 7:30 am?

i got an answer of 79 is that right?

Right.

ok i got 79 but when i write the equation do i write like this for my answer:

152 - 73 =79
There were 79 students in school by 7:30 am.

The answer is 79

To solve this problem, we can follow these steps:

Step 1: Set up the equation.
Let's represent the number of students at 7:30 am as "x". According to the problem, the number of students increased by 73 from 7:30 am to 8:00 am, resulting in a total of 152 students at 8:00 am. So, we can set up the equation: x + 73 = 152.

Step 2: Solve the equation.
To solve the equation, we need to isolate x by subtracting 73 from both sides:
x = 152 - 73.
Evaluating the right side of the equation gives us:
x = 79.

Step 3: Check the solution.
To check if this solution is correct, substitute x = 79 back into the original equation:
79 + 73 = 152.
152 = 152.

Since both sides of the equation are equal, we can conclude that the solution is correct. Therefore, there were 79 students in the school at 7:30 am. Your answer of 79 is correct.
