Step-by-step explanation:
therefore, the two digit numbers is 10× + y and reversed numbe is 10y + ×
Given:
x-y=3----1
Also given
10x+y+×= 143
11× + 11y =143
x+y = 13----2
Adding equation 1 and equation 2
2× = 16
×= 8
therefore, y = x - 3= 8- 3 = 5
Therefore, the two digit number = 10x + y = 10* 8 +5= 85
