Aflati X numar natural din egalitatile:
17+x=71
x-18=81
236=4x
3xori1997=0
x:19=1
1800=x:25
3x=1=94
5x-7=103
157-2x=49
117:x=13
4025:x=5
384:(x+2)=4
(2x-1):7=315
7x-9=82
3(x-1)+1=49
5ori(x-3)=215
Va rog din tot sufletul sa ma ajutati...nu ma pricep absolut deloc la matematica........va rog cat mai repede!!!

17+x=71 --- x=54
x-18=81 --- x=99
236=4x --- x=59
3x×1997=0 --- x=0
x÷19=1 --- x=19
1800=x÷25 --- x=45000
3x=1=94 --- x=?
5x-7=103 --- gresit pt ca 103-7=96 si 96 nu se imparte la 5
157-2x=49 --- x=103
117÷x=13 --- x=39
4025÷x=5 --- x=85
384÷(x+2)=4 --- x=192
(2x-1)÷7=315 --- x=?
7x-9=82 --- x=13
3×(x-1)+1=49 --- x=?
5×(x-3)=125 --- x=?
Eu ata am stiut,sper sa te ajute!
