Question

Afla numărul necunoscut din fiecare expresie după exemplul oferit. Metoda mersului invers!!
Ex: a+190 + 190÷ la 10 = 300
A +190 + 190 = 300 × 10
A +190 + 190 = 3.000
A + 190 = 3.000- 190
A + 190 =2810
A =2810- 190
A = 2620

244-hx5+(300-6x16)÷4=255
Va rog!!

Answer 1

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

244-h×5=204

h×5=244-204

h×5=40

h=40:5

h=8

Answer 2

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

244 - h × 5 = 204

h × 5 = 244 - 204

h × 5 = 40

h = 40 : 5

h = 8
