A) x= 5/7
b) x= 5/2
c) x= -1
Your answer should be:

Answer:
The 2 digit number is 36
Step-by-step explanation:
Let the 2 digits be x and y, then:
x + y = 9
10y + x = 27 + 10x + y
From the second equation:
-9x + 9y = 27 Divide through by 9:
-x + y = 3 Add this to th first equation:
2y = 12
y = 6.
and x= 9- 6 = 3.
