tim số nguyên x biết
5/6 = x -1/x
1/2 = x +1/3x
2x -1/3=3x +1/4
4/3=2x-1/x
tim x biet: ||x-1/2|.|2x-3/4||=2x-3/4
tim x(x-2)(3+2x)-(x-1)2=4(x-3)-(2+3x)2
Tim so nguyen x biet : -x/2+2x/3+x+1/4+2x+1/6=3/8
tim x
( 3 - 2x ) . (1/3 -1/2 ) ^ 2 + 4 . ( 7 - 5x ) = 9 - 2x
Tim x biet
A, 2x +23x = 625
B, (2^2+4^2) x + 2^4 ×5 ×x =100
C, (3x + 1)^2 = 6^2 + 8^2
D, (7x -11)^3 = 7^2 × 5^2 - 15^2
E, (2x- 1)^4 = 3× (3^2+4^3+2)
Tim x, biet:
a) (-5)-(x+5)=3-(2x-5)
b)2(x-3)-3(x-2)=3(x+1)-5(x-2)
C)4(1-2x)=(-3)-3(2+3x)
Giải ngay nhé, chiều mình đi học rồi.
giup mik voi tim x biet
1, 5-(3x+6)>-2x+1
2, -7.(x+2)-3x<6-11x
3, (x+1).(x+2)-x.(x+3)<4-x
4, 6-2x>17+(4-x)
Tim x
a,(2x-3) .(6-2x)= 0 b,x:3/4+1/4=2/3 c,-2/3-1/3.(2x-5)=3/2
