If or when there were only a male and female on the planet, wouldn't there be inbreeding and genetic diseases at first?

hi there /sci/ ive been working real hard today as i have a spec test tomorrow on logarithms and indices, no doubt you will most likely find this really easy but I lack the algebraic skills to break some of the complex questions down, I was wondering if I explained the problem someone could work through the question to help me understand.

1. 5(2^x) = 3 - 2^x+2

2. 5^x + 4(5^x+1) = 63

the problem im having comes with the multiplication, I dont know what to do when I have 4 groups of 5 to an unknown power. If someone could go through the question Id really appreciate it :)

why cant computers figure out the secrets of the universe

If time travel is possible, where have all the time travellers from the future been?
