Ta có : 5 + ( 2x - 1 ) = -6 - ( 5 + x )
=> 5 + 2x - 1 = -6 - 5 - x
=> 4 + 2x = -x - 11
=> 2x + x = -11 - 4
=> 3x = -15
=> x = ( -15 ) : 3 = -5

Mình t cho 5 bạn nhanh nhất
Tìm x:
\(\frac{x}{5}=\frac{1}{2}-\frac{1}{5}\)
\(\frac{1}{3}+\frac{2}{3}xX=\frac{18}{21}\)
\(\frac{3}{4}xX+\frac{x}{6}=\frac{1}{6}\)
\(2xX+3\frac{1}{2}+x=24\frac{1}{4}\)
13x(7-x)=26 (4x-18):3=2 2xx+98x2022=98x2023 (x+1)+(X+3)+(X+5)+.....+(X+101)
1+3+5+7+....+1993+1995+2xX =996006
TIM X NHA !
tim x :a.x^3=343;b.x^8/243=27;c.(1/2)^2xX=(1/2)^5;d.(1/3)^3xX=1/81;e.8/2^x=2
Tim x thuoc N sao cho \(\frac{2xx+5}{xx+1}\)(2x+5\x+1) la so tu nhien
CAC BAN GIUP MINH NHA thank you so much
tìm X :
2xX(X+5)+3 x (X+9)-15=135
(2xX-15)5=(2xX-15)3
