24:(9+x)=
(9+x)= 24:2
(9+x)= 12
x= 12- 9
x= 3
a.x/60=-3/4
b. 2/5=12/x
c. x-5/7 =6/21
dx+7/8 =63/24
e x/6=24/x
f .x+5= 4/x+5
g. x+12/x+8=4/3
h. x+9/x+7=9/8
tính
a)(-12)+(-9)
b)3^2 x 24 +3^2 x76
9^5 -3^2x3
tìm x
a)x-12=-28
b)20+8x(x+3)=5^2x4
)9^5 :9^3-3^2x3
-3x + 24 = -24
17 - 2x = -15
54 : ( x + 2) = -6
12 . ( 3 - x ) = 72
-3. ( x + 5) + 18 + -27
( x + 5 ) 2 = 9
( 3 - x )3 = 27
cần gấp ạ
trl đúng sẽ tick
Tim so nguyen x biet:
a,x-(-24)=3
b,(x+5)-(x-9)=x+3
c,c(x+2)=0
d,(x-1)^2=0
e,x^2-3x=0
f,-13-(6-|x+1|)=24
g,26-|x+9|=-13
i,(3x-6).3=3^4
Bài 2: Tìm x
a) x - 2/11 = -5/11
b) x - 1/24 = -1/8 + 5/6
c) 5/8 - x = 1/9 - (-5/4)
d) 8/23 . 46/24 - x = 1/3
e) 1/5 : x = 1/5 + 1/7
Tìm x biet
24/9-(x+1/2)^2=2/1/3
1) x/3=-9/x^2
2) -24/6=x/3=4/y^2=7^3/-2
Rút gọn biểu thức: a) 2x+(-81) - (24 - 81); b) (-9 - x + 2) + 9 c) 66 - (12 - x) + (12 - 66); d) 15 - (15 - x + 93)+ 93
-3(x-5)+6(x+2)=9
7(x-9)-5(6-x)=-6+11x
10(x-7)-8(x+5)=6(-5)+24
