Question

If ax + by = 1f16; cx + dy = 2510. Find the value of x and y?

Answer 1

= 1C9, y = 134

Solution : 

Changing it to Decimal,

10x + 11y = 7958 --> 1
12x + 13y = 9488 --> 2

1*12 => 120x + 132y = 95496 --> 3
2*10 => 120x +130y = 94880 --> 4

3 - 4 => 2y = 616 => y = 308

Substituting in 1 => 10x + 3388 = 79=> 10x = 4570 => x = 457

Hence x = 457, y = 308 (in Decimal)

So in Hex => x = 1C9, y = 134.

Answer 2
