The solution is shown in the graph.
x= 2.3
y= 4.3
Yes, it is a rational number.
49/100 I don't know how specific you needed it to be.
The answer is A. 42
Solution:
Let x= ones digit, y=tens digit
1st condition (original number) : 7(x+y)=10y + x
2nd condition (new number by reversing the digits): 18+x+y=10x+y
simplifying:
1st condition: 6x=3y
2nd condition: x=2
substituting x=2 to 6x=3y
