Question

Please solve this I have exam tomorrow

Answer 1

Answer:

(4,9)

Step-by-step explanation:

Let the numbers be x and x+5

According to question,

(x+x+5)² = 169

=> 4x² + 20x + 25 -169 = 0

=> 4x² + 20x - 144 = 0

=> x² +5x - 36 = 0

=> x² + 9x -4x -36 = 0

=> (x+9)(x-4) = 0

x = 4

x+5 = 9

Answer 2

Answer:

9+y=13

y=13-9

y=4

Therefore,X=9,Y=4
