34+(9-21)=3417-(x+3417)
34+(-12)=3417-3417+x
22=0+x
22=x
Vậy x=22
34+(9-21)=3417-(x+3417)
34+(-12)=3417-(x+3417)
22 =3417-(x+3417)
3417-22=x+3417
3395 =x+3417
3395-3417=x
x=-22
34+(9-21)=3417-(x+3417)
34+(-12)=3417-3417+x
22=0+x
22=x
Vậy x=22
34+(9-21)=3417-(x+3417)
34+(-12)=3417-(x+3417)
22 =3417-(x+3417)
3417-22=x+3417
3395 =x+3417
3395-3417=x
x=-22
34 + (9 -21) = 3417 - ( x +3417)
Tính
A, 34+(9-21)=3417-(x+3417)
B, (15-x)+(x-21)=7-(-8+x)
34+(9-21)=3417-(x+3417)
x-{55-[49+(-28-x)]}=13-{47[25-(32-x)]}
Tìm x thuộc Z biết :
A) 34+(9-21)=3417-(x+3417) B) x-(55-(49+(-28-x)))=13-(47+-25-32-x))
C)|x-1|-x+1=0 D) |2-x|+2=x
Giải ra giup minh nha !!!! MINH TICH CHO !!!!!
tìm x \(\in\)Z biết
a) 34+(9-21)=3417-(x+341)
b)(15-x)+(x-12)=7-(-8+x
c) x-{55-[49+(-28-x)]}=13-{47+[25-(32-x)]}
d) -7+lx+4l=-3
e) lx-10l-(-12)=4
tìm x biết: -24x + 7x + =3417
Tìm x thuộc Z,biết:
a) 2x + 3x = -150
b) -24x + 7x = 3417
c) -3x + x = -842
d) -7x + 2x = -450
viet so la ma
89, 169 , 234 , 376 , 495 , 1784 , 2396 , 2794 , 3417, 3659 , 3786 , 3985 , 3999
a)(x+12).(x-7)=0. b) 2x+3x=-150. C)-24+7x=3417. E)5.(x-2)-3x=-4
