4x+12y=56
x+y=8
multiply bottom equation by four
4x+12y=56
4x+4y=32
subtract the two equations
8y+24
divide both sides by eight
y=3
plug into original equation
x+3=8
simplify
x=5

so, is a
cubic trinomial.
Let s represent the number of students surveyed.
.. 0.40s play baseball
.. 0.60*(0.40s) play soccer and baseball
.. 0.60*0.40s = 12 . . . . . . . 12 students play soccer and baseball
.. s = 12/(0.60*0.40) = 12/0.24 = 50
