You can put this solution on YOUR website! X/2+X/10+X/20+35000=X
(10X+2X+X)/20+35000=X
13X/20-X=-35000
(13X-20X)/20=-35000 NOW COMBINE THE X TERMS & CROSS MULTIPLY.
-7X=-35000*20
X=-700000/-7
X=$100,000 ANSWER FOR THE TOTAL AMOUNT SAVE OR INVESTED.
PROOF
100000/2+100000/10+100000/20+35000=100000
50,000+10,000+5,000+35,000=100,000
100,000=100,000
