(20 inmultit (x:40 minus 24) inmultit 75 inmultit 100:15 minus 9980) inmultit 40 egal cu 800

Answer 1

(20*(x:40-24)*75*100:15 9980)*40=800// (20*(x:40-24)*75*100:15-9980)=800:40 =20//// (20*(x:40-24)*75*100:15)=20+9980 =10000/ /////20*(x:40-24)*75*100=10000*15=150000/// /20*(x:40-24)*75=150000:100=1500/ 20*(x:40-25)=1500:75=20/ x:40-24=20:20=1/// x:40=1+24=25/// x=40*25=1000//

Answer 2

(20x(x:40-24)x75x100:15-9980)40=800
20x(x:40-24)x75x100:15-9980)=800:40
(20x(x:40-24)x75x100:15-9980)=20
20x(X:40-24)x75x100:15)=9980+20
20x(X:40-24)x75x100:15=10000
(X:40-24)x75x100:15)=10000:20
(X:40-24)x75x100:15=500
(X:40-24)x75x100=500x15
(X:40-24)x75x100=7500
(X:40-24)x75=7500:100
(X:40-24)x75=75
x:(40-24)=0
x:20=0
x=20x0
x=0
