Tìm x biết a) f(2x-3)=3x+7
b) f(2x-7/x-3)=x=3/x-4(x khác 3,4)
c) f(x-1/x)=x+1/x^2 -4 (x khác 0)
Tìm x biết
a) f(2x-3)=3x+7
b) f(2x-7/x-3)=x=3/x-4(x khác 3,4)
c) f(x-1/x)=x+1/x^2 -4 (x khác 0)
Tìm x biết

a) 3 - | x + 7| - \(\frac{1}{2}\)= \(\frac{1}{3}\)
b) | x- 1,5 | + | x - 2,5 | = 0
c) 1,7 + | 3,4 - x | = 6
d) 5 . | x - 28 | -3,5 = \(\frac{1}{2}\)
e) | x- \(\frac{1}{2}\)| . (x + 1) = 0
nhanh mình dang gấp
a)\([x.\dfrac{1}{2}]^{3}=\dfrac{1}{27}\)
b)\([x+\dfrac{1}{2} ]^{2}=\dfrac{4}{5} \)
c) I 3x-4/5 I = 11/5
d) I 2x - 2I = 0
Tính
a, |5-3x|+2/3=1/6
b, -2,5+|3x+5|=-1,5
c, 11/5-|1/5-x|=3/5
d, |x-2/5|+1/2=3/4
các bạn ơi giúp mik với
a) (3x-5).(x+1)-(3x-1).(x+1)=x-4
b) (x-2).(x+3)-(x+4).(x-7)=5-x
c) 5.(x-3).(x-7)-(5x+1).(x-2)
d) 3.(x-7).(x+7)-(x-1).(3x+2)=13
