1. 4(k-8)=-32+4k
2, 6x+3-6x=3
3.:-28=-7(3x+4)+21x
4. 8(k-6)+58=2(4k+5)
5.12+4n=4(n+3)
6.-5(x-1)=5-5x
Can someone tell me if any of these have no solution, infinite solution

Sorry guys but as you have a small brain

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
