Giúp mik vs:33
17x + 3. ( -16 x -37 ) = 2x + 43 + 4x
giải hộ mk vs
Cho mình hỏi bài này với:
a/ 17x - ( -16x - 37 ) = 2x + 43
b/ -2x - 3. (x - 17 ) = 34 -2 ( -x+25)
c/ 17x + 3. ( -16 x -37 ) = 2x + 43 + 4x
Giải kỹ giùm nha. Thanks!
tìm x
a,-2x-(x-17)=34-(-x+25)
b,17x-(-16x-37)=2x+34
c,-2x-3.(x-7)=34-2(-x+25)
d,17x+3.(-16x-37)=2x+43-4x
e,-2x+3.{12-x[3x-(20+2x)-4x]+1}=45
cho mình hỏi
g, 17x+3.(16x-37)=2x+43-4x
BÊN DƯỚI NỮA NHÉ GIẢI GIÚP MÌNH ! help me
tìm số ngyên x :
a) -2x-(x-17)=34-(-x+25)
b) 17x-(-16x-37)=2x+43
c) -2x-3.(x-17)=34-2(-x+25)
d) 17x+3.(-16x-37)=2x+43-4
e) {-3x+2.[45-x-3(3x+7)-2x]+4x}=55
g)103-57; [-2.(2x-1)2 -(-9)0 ] =-106
tìm x
17x – ( -16x – 37) = 2x +
-2x –3. (x – 17) = 34 – 2(-x + 25
17x + 3. ( -16x – 37) = 2x + 43 - 4x
103 -57: [-2. (2x – 1)2 – (-9)0] = -106
3x – 32 > -5x + 1
15 + 4x < 2x – 145
-3. (2x + 5) -16 < -4. (3 – 2x)
-2x + 15 < 3x – 7 < 19 – x
x + (x+1) + (x+2) + (x+3) + .... + 13 + 14 = 14
25 + 24 + 23 +...+ x + (x - 2) + (x – 3) = 25
