Question

A two digit no is obtained by either multiplying the sum of digit by 8 and then subtracting 5 or by multiplying the difference of digits by 16 and adding 3 .find the number

Answer 1

1 st part

Let the no. be xy.
So,
xy = x+y + 8 - 5

2 nd part

Let the no. be xy.
xy = x-y × 16 + 3

So, the equation is
xy = x-y × 16 + 3 =xy = x-y × 16 + 3
