Answer:
x = 0
Step-by-step explanation:
Solve for x:
x/5 + 5 = 5
Put each term in x/5 + 5 over the common denominator 5: x/5 + 5 = x/5 + 25/5:
x/5 + 25/5 = 5
x/5 + 25/5 = (x + 25)/5:
(x + 25)/5 = 5
Multiply both sides of (x + 25)/5 = 5 by 5:
(5 (x + 25))/5 = 5×5
(5 (x + 25))/5 = 5/5×(x + 25) = x + 25:
x + 25 = 5×5
5×5 = 25:
x + 25 = 25
Subtract 25 from both sides:
x + (25 - 25) = 25 - 25
25 - 25 = 0:
x = 25 - 25
25 - 25 = 0:
Answer: x = 0

Answer:
60 students passed, and 75 appeared in examination.
Step-by-step explanation:
Let's say s is the total number of students and p is the number of students who passed.
80% of the students passed, so:
0.8 s = p
If there were 10 less passers, and 15 less students (5 less failures), then the ratio of passers to failures would be 5/1.
(p − 10) / (s − p − 5) = 5 / 1
Simplify the second equation:
p − 10 = 5 (s − p − 5)
p − 10 = 5s − 5p − 25
6p = 5s − 15
Substitute the first equation.
6 (0.8 s) = 5s − 15
4.8 s = 5s − 15
0.2 s = 15
s = 75
p = 0.8 s
p = 60
60 students passed, and 75 appeared in examination.
