4 (i literally had to think about this cause i thought it was too easy )
3m - 5p = 12
3m(-3m) -5p = (-3m)+ 12
-5p = -3m + 12
(-5)/-5p = (-5)/ (-3m + 12)
p = 3/5m + 12/-5

k and m must satisfy 8k = 1 mean k = ⅛
and 2km+⅝=0 mean m = -5/2
<span>It means to give a new name to someone or something.</span>
Is there any more to the question? i’m confused
