tim x biết
a)2|x-6|+7x-2=|x-6|+7x
b)|x-3|=2x+6
c)|x+1|+|x+2|+|x+3|+..+|x+2018|=3027x
Tim x biet
(7x-11)^3=(-3)^2x15+208
Tim x biet
(7x -11 )^3 = 2^5 x 2^2 +200
tim x
3/4x=1
4/7x=9/8-0,125
tim x
-2x(6x-2)+3x(4x-7)=8
(7x-2)(2x+3)-(3x-5)(4x+6)=2x2-5
+(-2x+3)-6x(3x-4)=-22x2+7x
2^x+1*2^2014=2^2015 tim x
7x-x=5^21/5^19+3*2^2-7 tìm x
(7x-11)3 =25.52 +200
tim x
tim x ,biet
A)3/4x=1
B)4/7x=9/8-0,125
tim x
a, 4-x / 2x + 1 = x-3 / 5 - 2 x
b,, 7x - 3 / 5x + 2 = 7x - 9 / 5x -5
