Question

a two digit number is five times the sum of its digit and is also equal to 5 more than twice the product of its digit find the number ​

Answer 1

Answer:

Step-by-step explanation:

Let the two digit no. be (10x+y)

According to the sum:

10x+y=5(x+y)----eq.1

10x+y=5+2xy---eq.2

Eq.1:

10x+y=5x+5y

6x=4y

x=4y/6

x=2y/3---eq.3

Substitute 3 in 2

10*2y/3+y=5+2[(2y/3)*y]

Solve this to get the value of y

Then substitute the value of y in eq.1 n find value of x
