eric got a score of p
steve got a score of 3p
e equal the score that eric got.
equation for eric is e = p
s equal the score that steve got.
equation for steve is s = 3p
s got 72 marks.
s = 3p
s = 72
replace s with 3p to get 3p = 72
solve for p to get p = 24

eric must have gotten 24 marks.
p = 24
e = p
e = 24
s = 3p = 72
