Question

Rezolvati :

a) x + 5 × (33 + 128) = 895

b) x - 53 × (49 - 3 × 12) = 996

​

Answer 1

Răspuns:

a) x + 5 × (33 + 128) = 895

x + 5 × 161 = 895

x + 805 = 895

x = 895

b) x - 53 × (49 - 3 × 12) = 996

x - 53 × (49 - 36) = 996

x - 53 × 13 = 996

x - 689 = 996

x = 1685

Answer 2

Răspuns:

Salutare!

a)

x+5×(33+128)=895

x+5×161=895

x+805=895

x=895-805

x=90

verificare: 90+5×(33+128)=

90+5×161=

90+805=

895

b)

x-53×(49-3×12)=996

x-53×(49-36)=996

x-53×13=996

x-689=996

x=996+689

x=1 685

verificare: 1 685-53×(49-3×12)=

1 685-53×(49-36)=

1 685-53×13=

1 685-689=

996
