Let the number of pounds of corn meal be x and the number of pounds of soybean meal be y.
x + y = 240, for obvious reasons.
(0.06 x + 0.12 y)/240 = 0.1 (the fracttion that is protein)
Solve those two equations for x and y, using algdebra.
The sccond equation can be rewritten as
0.06x + 0.12y = 24, or
x + 2y = 400
Take it from there
