\(\Rightarrow3^x=\dfrac{36-1}{4}=\dfrac{35}{4}\Rightarrow x\in\varnothing\)
\(\Leftrightarrow3^{x+1}=9\)
nên x+1=2
hay x=1
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
-1/4-3/4÷x=11/36
Tim x la phan tu cua N biet
a ) ( x - 5 ) x 4 = 36
b) ( 48 - x ) x 2 = 14
c) ( 2 x X - 3 ) x 5 = 4
d) 1 + 3 + 5 +..........+ X = 36
e) 1 + 2 + 3 + ...........+ X = 55 + 6 +.....+ 2X = 110
1) 4/7 x - 2/3 = 1/5
2)1/2 x + 3/4 = -3/10
3)x+7/15 = -24/36 (giúp với ạ) :D cảm ơn ạ
a)x-1/9=8/3
b)x/5=5/6+-13/30
c)3/4+1/4:x=-1
d)1/4-5/18<x/36<-8/5+1(x(-z)
giúp mik với
(1/3.x+1/4) mũ 2= 1/36
(2x+1)^3=125
(2x-1)^4=16
6.3^x-2.3^x=36
2^x+1-2^x=32
Tìm các số nguyên x,y biết : a,-1/3<x/36<y/18<-1/4
b, -7/12<x-1/4<2/3
tim x
4.(x+3)-2.x=36
1+3+5+...+x=250
Tìm x, biết: a) x = 1/4 + 5/13 b) x/3 = 2/3 + -1/7 c) x/3 = 16/24 + 24/ 36
d) x/15 = 1/5 + 2/3
