Tìm số nguyên x, biết: a) 12 + (2x - 11) = 53; b) 21 - (-6+ 3x) = 9 c) - (2x + 4) + 11 = -27; d) 33 - (33 - x) = 0
x+-1/2=3
x-3/4=4/3
3/4+(x-1/2)=5/6
3x - 36=12 . 75 + 25 .12
x:2-12=33 . 40 + 33 . 59 +33
(x-4) . (9-x) = 0
(x-6) . (2020-x)=0
x . (6-x) =0
(x-3-12) . (20-x)=0
Giúp em vs ạ em cảm ơn(◕ᴗ◕✿)
tim so nghuyen x biet:
a, 12+(2x-11)=53
b, 21-(-6+3x)=9
c, -(2x+4)+11=-27
d, 33-(33-x)=0
(x+5)(y-2)=13
(3x-5)(y-6)=17
(X-1)(x+y)=33
bài 1:
1) 20 - 2(x+4)= 4
2) 30 - [ 4(x-2)+ 15]= 3
3) 14 ⋮(2.x + 3)
4) (3x - 24).7 = 2.73
5) (x + 1)3 = 27
6) (2x - 6).47=49
7) (10 + 2x) : 42011 = 42013
8) [(8x - 12) :4].33 = 36
9) 6⋮(x - 1)
10) (x + 5)⋮(x + 2)
mong mn giúp mình gấp với ạ ^^
a, 3x = -75
b, x/7 = -6/8
c, -5/6 + x = 7/12 - 1/3
d, 1/2x - 33/55 = 20/50
a. 219 - 7(x + 1) = 100 b. ( 3x - 6).3 = 36 c. 716 - (x - 143) = 659
d. 30 - [4(x - 2) + 15] = 3 e. [(8x - 12) : 4].33 = 36
a) 5(x+35)=515
b) 12x-33=3².3³
c) 6.x-5=19
d) 4.(x-12)+9=17
e) 123-5.(x+4)=38
f) (3x-2⁴).7³=2.7⁴
