You can put this solution on YOUR website!
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

equation for eric is e = p
eric must have gotten 24 marks.

p = 24
e = p
e = 24
s = 3p = 72
