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
Tìm số nguyên 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.(-16-37)=2x + 43 -4x
e) {-3x + 2.[45 - x - 3(3x + 7)-2x] + 4x}=55

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!
