I am a number between 60 and 100. My ones digit is two less than my tens digit. I am a prime number. What number am I?

100+60+x x=? to figure out the problem, you look at hundredth digit. 100 but wait. 100+60 in expanded form is 160. 160x to figure out x, you need to subtract 2 from 60. Which is 58. Unless it's 2-6. 2-6=4. in expanded form, the answer is 100+60+4 but we speak numbers so in the number form, it would be: 164 so x=4
