The steps are duplicated.Then, first I will write the steps in the right form:
19 = 5x - 1
20 = 5x
4 = x
Now, I will write the steps with the justification
19 = 5x - 1.... start
20 = 5x ..... Reason: addtion property of equality (you get this by adding +1 to both sides of the previous equality)
4 = x .... Reason: division property of equality (you get this by dividing by 5 both sides of the previous equality)
To change 1/2 to 3/4 you multiply by 3/2 so then multiply 3/4 by 3/2 and you get 6/6 or 1...the answer is 1
So the initial question is x / 113 = 3.14 (we're keeping it a smaller decimal for now)
What you should do first is multiply both sides by 113
Your answer should be x = 354.82
Round this up to x = 355. <-- This is why we only used 3.14 at the start
Now check your work:
x / 113 = ?
355 / 113 = 3.14159265358979... which essentially is pi
