tim x a,1/3x-4/3=5 b,2/3x+1/2=2 c,3-3/4x=x-5
bai 1 tim x biet;
1) 3x - 6 = 5x + 2
2) 15 - x =4x - 5
3) x - 15= 6 + 4x
4) -12 + x=5x - 20
5) 7x - 4 =20 + 3x
tìm X
1/4+2.(3.x-2/3)=1
(1/2+2X). (2x-3)=0
(4x-5).(5/4.x-2)=0
1/9-(2.x+1/2)mũ 2=0
9.(3x-1/2)mũ 2 =4
1/2.x+2/3.x-1=-10/3
X+1/12=-3/9
Tim x
1) 5x = 120 : 2
2) 3x + 27 = 45
3) 73 + x - 122 = 234 : 2
4) 32 - 2 ( x -1 ) = 12
5) 3 ( x + 1 ) - 15 = 36
6) 21 - ( 4x - 16 ) = 21
7)13 x - 3x = 500
8) 9x + x - 35 = 65
Giup e nha, em can gap
Tìm x biết
1)3/4x-1/4=2(x-3)+1/4x
2)30%.x-x+5/6=1/3
3)8/9x-2/3=1/3x+1 1/3
tim x:
a, 3(2x+3)(3x-5)<0
b, 2x2 - 4x>0
c, 5(3x+1)(4x-3)>0
Tìm x 5/11-3x=2/3x-2;x-11/x-3=2/3;-4x-3/4=1-3x/3 giải giúp em nha
