If you can give me equations with the varbile x on both sides that equal 16 you can have my points and ill you also so what is an equation that x=16

I'm not sure if this is what you wanted, but here:

-8x+11 = 8x-5

-> Solving this gives you x = 16

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
