Question

e si f va roooggg cu metoda mersului invers

Answer 1

e)369-[(x+122):5+113]=434. 369-[(x+122):5]=434-113. 369-[(x+122):5]=321 [(x+122):5]=369+321. [(x+122):5]=690. (x+122)=690:5. (x+122)=138. x=138-122. x=16. f)104:[(x-3•8)•2:8]=13. 104:[(x-24)•2:8]=13. 104:[(x-24)•2]=13•8. 104:[(x-24)•2]=104. 104:[(x-24)]=104:2. 104:[(x-24)]=52. (x-24)=104:52. (x-24)=2. x=24+2. x=26. Sper ca te-am ajutat !!!
