Question

Rezolvati multimea numerelor naturale ecuatiile:
a) 20x+24=6264
b) 9x-53=313*4
c) 3756+4705-3x=17017
d) 11x-10988=12
e) 5x+748=2x+1456
f) (702:x-37:5):5=19
g) (86:x+54:x):2=35

Va rooog este urgent dau coroana!!!!!!!!!!!!!!!!!

Answer 1

a) 20x = 6264-24
   20x = 6240/20
      x = 312
d) 11x = 10988+12
       x = 11000/11
       x = 1000
e)5x-2x = 1456-748
   3x = 708
     x = 708/3
     x = 236
Atat am stiut sa rezolv.Sper ca te am ajutat.

Answer 2

a)20x+24=6264
20x=6264-24
20x=6240
x=6240:20
x=320

b)9x-53=313*4
9x-53=1252
9x=1252+53
9x=1305
x=1305:9
x=145

c)3756+4705-3x=17017
8461-3x=17017
3x=17017-8461
3x=8556
x=8556:3
x=2852

d)11x-10988=12
11x=10988+12
11x=11000
x=11000:11
x=1000

e)5x+748=2x+1456
5x=2x+1456+748
5x=2x+2204
5x+2x=2204
7x=2204
x=2204:7
x=314

f)(702:x-37:5):5=19
702:x-37:5=19*5
                =95
702:x-37=95*5
              =475
702:x=475+37
          =512
x=702:512
x=1,34

g)(86:x+54:x):2=35
(86+54):x=35*2=70
140:x=70
x=140:70
x=2
