Question

If 10 be added to four times a certain number the result 5 less than five times the number. Find the number

Answer 1

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.
