tìm x biết
a){x-[5^2+(3^5-80.3)^3-51]^50+14}=20
tìm x biết
a)680-(5x+60)=425
b){x-[5^2+(3^5-80.3)^3-51]^50+14}=20
Bài 1 : Tìm số tự nhiên x biết :
a)680-(5x+60)=425
b){x-[5^2+(3^5-80.3)^3-51]^50+14}=20
a) 2/3+1/3:x=3/5
b) 10/3x +67/4=-13,25
c) x+30℅x=-1,3
d) (14/5x -50):2/3=51
e) 2/5+3/5.(3x-3,7)= -53/10
f) 2/3x -3/2x =5/12
(14/5 × X - 50) : 2/3 =51
Ai làm nhanh đúng mk cho 3 tk

Tìm x nha mn
Tìm x thuộc N biet
1) 19+(x-23)=50
2)(273-x) -140=34
3)56-(x-14)=22
4)172-(137-x)=93
5)13.(x-14)=91
6)(13-x).17=51
tìm x: biết :
( 2 4/5 .X-50) :2/3 = 51
2/3 X = 5/12
-2/3 X + 1/5 = 3/10
5 4/7 : X =13
