Câu cuối ban viết rõ lên nhé
Bài 1 : Tìm số x biết :
a) 2/3.x-3/2.x=5/12
b)2/5+3/5.(3x-3,7)= -53/10
c)7/9:(2+3/4x)+5/9=23/27
d) -2/3.x+1/5=3/10
e) |x|-3/4=5/3
f) |2x-1/3|+5/6=1
tìm x biết:
a)2/3x-3/2x=5/12
b)2/5+3/5.(3x-3,7)=-53/10
c)7/9:(2+3/4x)+5/9=23/27
d)-2/3.x+1/5=3/10
e)|x|-3/4=5/3
f)|2x-1/3|+5/6=1
giúp mik vs mik đang cần gấp bn nào giải mik cũng tick nha
giải hết giúp mik các bn nhé
a) 2/3 x -3/2 x =5/12
b)2/5 + 3/5.( 3x -3,7) =-53/10
c) 7/9 : ( 2 +3/4 x) + 5/9 = 23/27
d) -2/3 x + 1/5 =3/10
e) |x| - 3/4 =5/3
F) |2x - 1/3| + 5/6 = 1
A)2/5+3/5.(3.x-3,7)=-53/10
b)7/9:(2+3/4.x)+5/9=23/27
c)|2.x-1/3|+5/6=1
bai 1 : tinh nhanh :
a) -3/7+ 15/26 - (2/13 - 3/7 ) b) 2.3/7+(2/9-1\(\frac{3}{7}\)) - 5/3 : 1/9 c) -11/23 . 6/7 + 8/7 .-11/23 - 1/23 d) ( 377/231 - 123/89 + 34 /701 ) . ( 1/6 - 1/8 -1 /24)
bai 2 . tim so x biet :
a ) 2/3x - 3/2x = 5/12 b) 2/5 + 3/5 . ( 3x-3,7) = -53/10 c) 7/9:(2+3/4x)+5/9=23/27 d,-2/3.x +1/5=3/10 e, /x/-3/4=5/3
f, /2x-1/3/+5/6=1
2/3x-3/2x=5/12
b)2/5+3/5.(3x-3,7)=-53/10
c)7/9:(2+3/4x)+5/9=23/27
a) 2/5 + 3/5 . ( 3x - 3,7 ) = -53/10
b) 7/9 : ( 2 + 3/4x ) + 5/9 = 23/27
tim x
2/5+2/5.(3.x-3,7)=-53/10
7/9 / (2+3/4.x)+5/9=23/27
Tìm x
a, ( x-1/2 ):1/3+5/7=9 5/7
b, x+3/-15=1/3
c, 3/4x - 2/3x = 5/2
d, (3 1/2+2x).2 2/3=5 1/3
e. (2,8x - 32):2/3=-90
f, (2/11+1/3). x=(1/7-1/8).56
g, 1/4+1/3:(2x-1)=-5
h, 7/9:(2+3/4x)+5/9=23/27
i, |2x-1/3|+5/6=1
j, 17-(43-|x|)=45
