\(\left(3x-6\right)\cdot3=34\\ =>3x-6=\dfrac{34}{3}\\ =>3x=\dfrac{34}{3}+6\\ =>3x=\dfrac{52}{3}\\ =>x=\dfrac{52}{3}:3\\ =>x=\dfrac{52}{3}:3\\ =>x=\dfrac{52}{9}\)
(3x – 6).3 = 34
219 – 7(x + 1) = 100 ; b) (3x - 6).3 = 34
Tìm x, y biết
a,/2x/+/y-3/=0
b,/3x-6/+/3x-y+5/=0
c,34-2./9-3x/=0
tìm x thuộc Z
-2(-34-7x)+5c(-3x-14)=2
-13(-7+3x)-(-985+91)=20(-34-x)-6(3x-16)
Tìm x thuộc N
b, ( 5x + 34 ) . 6^8 = 3^4 . 6^9
c, 5^3 ( 3x + 2 ) : 13 = 10^3 : ( 13^5 : 13^4 )
(3x-6)x3=34
Bài 6: Tìm số nguyên x,biết:
|
a) x+ 118 =218 |
b) 18 – x =-17 |
c) (-18) – x =-17 |
|
d)124 +(118 – x)=217 |
e) (3x – 6).3 = 34 |
g) 23.(42 – x) = 46 |
|
h) 84 – (3x + 8) = 34 |
i) 3(2x + 1) -19 = 14 |
k) 6x – 302 = 23.5 |
|
m) (x -1)2 = 81 |
n) 2x+1- 5 =27 |
m) 2x+ 2x+1+ 2x+2 = 56 |
120 + ( 34 + 3x ) + ( 6 + x ) = 0
Tìm số nguyên x,biết:
1)-(-3)3-(2x+1)3=152
2)-(x+6)-34=12+3x
Làm hộ mik nhaaaaa.Cảm ơn
Tìm x biết:
a, 5(x – 7) = 0
b, 95 – 5(x+2) = 45
c, 6 2 x + 2 3 + 40 = 100
d, 3(3x+9)+6 = 96
e, 2 6 + 5 + x = 3 4
