Question

(i)Seven times 2 digit number is equal to 4 times the number obtained by reversing the digits. Represent this situation algebraically, what will be the equations you will get finally after simplification (write answer without leaving any space in the form ax+by+c=0)for first situation?

Answer 1

Answer:

7x - 4y + 0

Step-by-step explanation:

Let the digits of two digit number be ab

Number we obtain on reversing the digits = ba

Therefore, 7 (ab) = 4 (ba)

Now lets take the (ab) as (x) and (ba) as (y)

So, the relation will be 7x = 4y

Equation is ax + by +c

Here, a =7

b = -4

c = 0

Therefore equation is 7x - 4y + 0
