bài 1: tìm x:
a) x+(x+1)+(x+2)+.....+(x+2003)=2004
b) 7/3+(x-3/2)=(3-3/2).x
tìm x,biết:
(2x-3)-(x+2)=(x-2)-3(x-5)
Tìm x:
a) 5 - 4 (x - 2) = 3 . (2 -x)
b) 2 - 3 (x + 1) = x - 7
Tìm x:
\(\left(x-1\right)^3-2\left(x-1\right)\left(x+2\right)=\left(x+2\right)^3-3\left(x-1\right)^2+2\left(x+2\right)^2\)
1) Tìm x
a) -5.(x+1/5)-1/2.(x-2/3)=3/2.x-5/6
b) 3.(x-1/2)-5.(x+3/5)=-x+1/5
c) /x/ - 38/7./x/-3/4=2./x/+(-8/7)
/x/ là giá trị tuyệt đối nhé các bn
Tìm x:
a)\(\frac{x+7}{x+4}=\frac{2}{5}\)
b)\(\frac{2\text{x}-3}{2}=\frac{50}{2\text{x}-3}\)
c)\(\frac{x+1}{x-3}=\frac{x+3}{x+2}\)
Tìm x : \(\left(x-3\right)^2-\left(2x+1\right)^2-2\left(x-1\right)\left(x+2\right)=3\left(x-3\right)-\left(4x-1\right)\left(x+2\right)\)
Tìm x biết
a,|x-1|+2x=3
b,|x+1|+|x+3|=10-4x
c,|x+1++3|x-2|-5|4-x|=13-2x
d,3|x-2|-2|x+5|+4|x-1|=9-7x
Tìm x :
3(x+2)=5(x-3)-x
