(x –15) .15 = 0 b) 32 (x –10 ) = 32
c) ( x – 5)(x – 7) = 0 d) (x – 35).35 = 35
Tìm x biết:
a) x - 280 : 35 = 5.54
b) (x - 280) : 35 = 56 : 5
c) x : 15 + 42 = 13 + 25.8
d) (x - 128 + 20) : 192 = 0
e) 460 + 85.4 = (x + 200).4
f) x + 5.2 - ( 32 + 16.3 : 16 - 15) = 0

các bạn làm đầy đủ giúp mik với
Tìm x :
a. ( x - 15 ) .35 = 0
b. 32 ( x - 10 ) = 32
Nhớ trình bày cách làm .
Tìm x, biết
a) 575 – (6X + 70) = 445
b) (32.15) : 2 = (X +70) : 14 – 40
c) (X – 15) -75 = 0 d) 420 + 65.4 = (X + 175):5 +30
e) X – 4867 = (175.2050.70) : 25 + 23 f) [(X + 32) -17].2 = 42
g) 96 – 3.(X+1)=42 h) 165 – 19.(35 : X + 3) = 13
Tìm x
a, [ x - 15 ] . 15 = 0
b, 32 . [ x - 10 ] = 32
c, [ x - 15 ] - 75 = 0
d, 575 - [ 6x + 70 ] = 445
e, 315 + [ 125 - x ] = 435
f, 541 + [ 218 - x ] = 735
g, [ x - 36 ] : 18 = 2
h, 70 - 5 . [ 2x - 3 ] = 45
k, [ 2x - 39 ] . 7 + 3 = 80
m, [ x - 5 ] . [ x - 8 ] = 0
a) a- (10-x) = 7
b)-32 (x-5)= 0
c)11+(15-x)=1
d) x-{[x+(x+3)] - (x+3) - [(x-2)]=0
tìm x biết
a , \(\dfrac{-3}{10}\)-(\(\dfrac{-1}{5}\) +x)=\(\dfrac{-3}{2}\)
b, -(-x+ \(\dfrac{3}{4}\))- \(\dfrac{12}{8}\).- \(\dfrac{32}{15}\)=- \(\dfrac{-1}{2}\)
c, \(\dfrac{x-3}{x+5}\)=\(\dfrac{4}{3}\)
