Answer:
Let's name the digit:
x- ones digit
y - tens digit
we know that x=y-2.
Now, y can be 6,7,8,9 (the number is between 60 and 100 (so depending on your understanding of "between", 0 is also possible. but then the number would have to have -2 as its ones digit, so in any case, it's not possible).
So the possibilities with x=y-2:
64
75
86
97
Out of those 64 and 86 are even, so they can't be prime.
75 has 5 in its ones number: it's divisible by 5.
so the correct answer is 97.

Answer:
x=−2y+4
Step-by-step explanation:
1. flip equation
−1/
2
x+1=y−1
2. add -1 to both sides
−1
/2
x+1+−1=y−1+−1
−1
/2
x=y−2
3. divide both sides by (-1)/2
I really hope you understand the steps.
