1. tìm số nguyên x
a)-2x-3.(x-17)=34-(-x+25)
b)-2x-3.(x-17)=34-2(-x+25)
c)17x-(-16x-37)=2x +43
tìm số nguyên x
-2x-(x-17)=34-(-x+25)
17x-(16x-37)=2x+43
-2x-3(x+17)=34-2(-x+25)
17x+3(16x-37)=2x+43-14x
-2x+15<3x-7<19-x
25+24+23+.....+x+(x-2)+(x-3)
nhanh lên nha
a) -2x - (x-17) = 34 - ( -x+25 )
b) 17x - ( -16x - 37 ) = 2x+43
c) -2x - 3.(x-17) = 34 - 2.(-x +25)
d) [ -2. (2x-1)2 - (-9)0 ] = -106
GIẢI GIÚP MIK VỚI GẤP LẮM !!!
-2x-(x-17)=34-(-x+25)
-2x-(x-17)=34-(-x+25)
-2x-(x-17)=34-(-x+25)
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
Giúp mik vs:33
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 , biết :
1> -2x-(x-17)=34-(-x+25)
2> 17x-(-16x-37) = 2x=68
-2x-3.(x-17)=24-2(-x+25)
