Tim X :
a)x:1/3+2/3[1/5-1] =4
b)1/2 [x-3/5]=-1/3[7/6-3/2]
c)1/3-3/4=3/5 -x
d)4/7x-2/3=1/3+x
1.(-86-x)-(3+2x)=-4-15

Tìm x :
/x-5/ = /2x-1/
/x-7/ = -5
A. 5x=6×(x-1)
B.1×(3x)=(x+1)×2
C.3×(2x+1)=5×(x+2)
D.5×(7-x)=-4×(8x-2)
Tìm các số nguyên x biết :
a) 73 - 3x = 5.(1 - x) + 8 b) /2 - x/ + 1 = 3^5 : 3^3
Tìm số nguyên x, biết:
b) x - ( 1 - x ) = 5 + ( -1 + x )
Tìm x biết :
a) -2×(x-1/3)-5× (x+1/3)=1/2×x
b) -(1/2×x-3/4)-(-x+1)=-3/2
Cảm ơn nhiều nha!
