Answer 1

Explicație pas cu pas:

(3x+164):10=(56-54)•100-199+3

(3x+164):10=2•100-196

(3x+164):10=200-196

(3x+164):10=4

3x+164=4•10

3x+164=40

3x=40-164

3x=-124

x=-124:3

×=-41,(3)

Answer 2

(3x+164):10-3=(7*8-9*6)*100-199
(3x+164):10-3=(56-54)*100-199
(3x+164):10-3= 200-199
(3x+164):10-3= 1/+3
(3x+164):10=4/*10
3x+164=40/-164
3x= -124/:3
=> x=-41,(3)
