Tìm x thỏa mãn:
lx-1I+I1-xI=4-x
Tìm GTNN của:
a) A= I x - 7 I + 3 - x
b) B= I x+ 7I + I x + 3I + I x + 1I
c) C= I 2 - xI + I 5 - xI
Tìm x
Ix-3I+I1-xI=x+5
Ix-4I+I3-xI=1-2x
I2-xI+2=x
Ix-1I-x+1=0
Ix-1I=I2-xI
tìm x
I1-2xI-I2x-1I=8
bài 1 ; tìm x
a,2x+1=3x-5
b,2.(x-2)=5x-1/2
c,Ix-1I=1/2
d,I2-3xI+1/2=2/3
e,1/2x-2/3=1/4
j,3.(2x-1)=x-2
g,I1/2x-1I=1/3
h,I3x-2I-1/2=1
CẢM ƠN NHÉ
tìm x
I3x-1I+I1-3xI=6
nhanh nha

tim x :
a) I x+1I+I x -2I+I x+3I = 6
b) 2Ix+2I+I4-xi= 11
c) IxI - I 2x+3I = x-1
