11*{ X-6 } = { 4 * X } +11. tìm X
Tìm X biết:
a, 11 x ( X- 6 ) =4 x X + 11
b, ( 2 x X - 10 ) x ( 25 - 25 x X ) = 0
Tìm x
a) 1/2 : 3 + x = 14/5
b) 8/5 : x : 7/4 = 11/6
c) 24/10 + x : 3/4 = 11/3
Tìm x :
a) x.3 - x : 3 = 36,5.4
b) (x + 1 ) + (x + 4 ) + ( x + 7 ) + ... + ( x + 28 ) = 156
c) 11 .( x - 6 ) = ( 4.x ) + 11.
tìm x:
11 * ( x - 6 ) = ( 4 * x ) + 11
Tìm a
11 x (a-6)=(4 x a)+11
Tìm x :
12 : x + 5 = 3 + 25 : 5
170 - 5 x ( x + 19 ) = 50
11 x ( x - 6 ) = 4 * x + 11
Tìm X biết 11x (X-6)=4 x X+11
Tìm x:
a, 3/4 : x / 6 = 0, 75
b, 2,5 . 45 / x = 5 / 6
c, x / 12 + 121,5 = 121, 5
d, [3.x - 0,8 ]: x + 14,5 = 15
e, 6/8 = 15/x
g, 11. [x - 6 ] = 4 . x + 11
