PLEASE THIS IS LIKE I AM SUPER STUCK

Solve 2x+y=3 x+y=5 in substitution method

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2 acellus answer

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18 }, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
