Question

2306-c+2977=4285

698+i-450+367=1203
Buna va rog ajutati-ma!

Answer 1

2306-c+2977=4285

-c=4285-5283

c=998

698+i-450+367=1203

i=1203-615

i=588

Answer 2

2 306 - c + 2977 = 4 285

2 306 - c = 4 285 - 2 977

2 306 - c = 1 308

c = 2 306 - 1 308

c = 998 → numarul, aflat prin metoda mersului invers

_________________________________________

698 + i - 450 + 367 = 1 203

698 + i = 1 203 - 367 + 450

698 + i = 836 + 450

698 + i = 1 286

i = 1 286 - 698

i = 588
