Please show and explain all steps so I can better understand :)thx
The correct answer is 61
The correct option is option b) 61
What is linear equation in one variable and how to solve such equations?
Linear equation are the equation in which degree of the variable is one and only one variable is present in the equation. To solve is to find the value of the variable and to do that we first separate the variable from the constant and then find the value of the variable
We are given an equation
To solve the equation is to find the value of the variable x and to do that first we take is to square the equation both sides
We get
x + 20 = 81
Now we separate the variable and the and the constant to find the value of the variable we get
x = 61
Hence the correct answer is 61 and correction option is option b)

Step-by-step explanation:
There's a website called "symbolab.com" that I use to figure out problems like this easily. :) It has a bunch of math-related calculators and graphing stuff.
Basically there are 180 days in a school year so if a school buss is late 24 times in 30 days it will be late 168 times in a school year not counting the last days which will be exactly 173 late buses in a whole year .
Hope this helped :)
