Question

Metoda mersului invers

20×e - (1950+550):100=6175

35×f+(800-752:4):2=551

g:25+(100-1632:51)×2=286

244-h×5+(300-6×16):4=255
Va rog ajutati-ma. Dau coroana

Answer 1

20×e-2500:100=6175
20×e-25=6175
20×e=6175+25
20×e=6200
e=6200:20
e=310

35×f+(800-752:4):2=551
35×f+(800-188):2=551
35×f+612:2=551
35×f+306=551
35×f=551-306
35×f=245
f=245:35
f=7

g:25+(100-1632:51)×2=286
g:25+(100-32)×2=286
g:25+68×2=286
g:25+136=286
g:25=286-136
g:25=150
g=150:25
g=6

244-h×5+(300-6×16):4=255
244-h×5+(300-96):4=255
244-h×5+204:4=255
244-h×5+51=255
244-h×5=255-51
h×5=244-204
h×5=40
h=8
