Question

rezolva întâi operațiile din paranteză apoi calculează termenul necunoscut. x-(6350+13650)=5000,×+(2×3×9)=1100,×-(64÷8×3÷6=9997,(105301-95205)+×=100000,(25444+145556)-×=77777,(2408+26382)+×=400010,(1000000-77777)-×=1.​

Answer 1

Răspuns:

x-(6350+13650)=5000

x-20000=5000

x=5000+20000

x=25000

×+(2×3×9)=1100

x+54=1100

x=1100-54

x=1046

×-(64÷8×3÷6)=9997

x-(8x3:6)=9997

x-(24:6)=9997

x-4=9997

x=9997+4

x=10001

(105301-95205)+×=100000

10096+x=100000

x=100000-10096

x=89904

(25444+145556)-×=77777

171000-x=77777

x=171000-77777

x=93223

(2408+26382)+×=400010

28790+x=400010

x=400010-28790

x=371220

(1000000-77777)-×=1

922223-x=1

x=922223-1

x=922222
