We just started proofs in my mathematical structures class so this is the first time i am dealing with proofs.

The question i am having trouble proving is:

**Suppose x is a real number and x 0. Prove that if then **
This is what i have started:

**Givens:**
x is a real number

x

0

**Goals:**
i feel like to complete this proof you would solve the equation

for x and then this would show that whatever this value of x is, it will not be equal to 8.

The problem i am running into is that i cannot solve the equation

for x equaling a value, so i feel like i may be going about this wrong.

Any help / tips for proofs would be very great

Thank you
