4x+2.25(70-x)=3*70
\n" ); document.write( "4x+157.5-2.25x=210
\n" ); document.write( "4x-2.25=210-157.5
\n" ); document.write( "1.75x=52.5
\n" ); document.write( "x=52.5/1.75
\n" ); document.write( "x=30 pounds of cashews is used.
\n" ); document.write( "70-30=40 pounds of peanuts is used.
\n" ); document.write( "Proof:
\n" ); document.write( "4*30+2.25*40=210
\n" ); document.write( "120+90=210=210\r
