Tìm x:
a, (x - 1/2) : 1/3 + 5/7 = 9 5/7
b, x + 30% x = - 1,31
c, -2/3.x + 1/5 = 1/10
bài 1: tìm x
a) 8/23 . 46/24 = 1/3 . x
b) 1/5 : x = 1/5 - 1/7
c) 4/9 - (x - 1/2) mũ 2 = 1/3
d)3,2 . x - (4/5 + 2/3) : 3 2/3 = 7/10
Bài 1 : Tìm x biết
b) 1/2 . ( 4/5 -3/2 ) + x = 5 . (x - 1/3)
c) 2.( x-5) -3 . (x + 7) = 14
d) -8. / x -3/ = - 32
e) -90 :/ x+3/4 / = -45
tìm x :
A, (2x+1)^3=2^3 . 5^2 - 75
B, tìm x, y là số nguyên : x . Y - x + y = 4
C, tìm x, y là số tự nhiên : 5^x+12^y=26
Tìm x:
(3 1/2 + 2x) x 2 2/3 = 5 1/3
Tìm x biết
a) 4/5 + x = 2/3
b)3/4 - x = 1/3
c) x - 5/9 = -2/3
d)(4,5 - 2x) : 3/4= 1 1/3
Tìm x, biết:
(-3+3/x-1/3):(1+2/5+2/3)=-5/4
TÌM SỐ NGUYÊN X BIẾT
3/2/3.(1/5-1/2)< x<3/11.(1/5+2/3-1/2
5/3-x+1/5=-3/10
x-(1-1/4)=2/3
1-5/3=1/5-x
