Answer:
The certain number is 15 which results in 5 less than five times the obtained number.
Solution:
Let us assume that number would be a.
10 be added to 4 times of assumed number a in which the result is 5 less than 4 times of assumed number a.
Equation form: 4a + 10 = 5a – 5
By solving: 5a – 4a = 10 + 5
a = 15
When we substitute the value of a in the equation formed from the statement, both L.H.S AND R.H.S are equal.
