Question

rezolva prin metoda mersului invers

20*e-(1950+550)/100=6175

35*f+(800-752/4)/2=551

G/25+(100-1632/51)*2=286

Answer 1

20×e-(1950+550)÷100=6175

20×e-2500÷100=6175

20×e-25=6175

20×e=6200

e=6200÷20=310

35×f+(800-725÷4)÷2=551

35×f+(800-181,25)÷2=551

35×f+618,75÷2=541

Answer 2

Răspuns:

Explicație pas cu pas:

G/25+(100-1632/51)*2=286

G/25+(100-32)*2=286

G/25+68=286/2=143

G/25=143-68=75

G=75*25

G=5100
