Tìm số nguyên x:
a,-2x+15<3x-7<19-x
b,-2x +3.{12-2[3x-(20+2x)-4x]+1}=45
c,{-3x+2.[45-x-3(3x 7)-2x] 4x}=55
Ai làm nhanh và đúng, mik tick
Tìm số nguyên x:
a) 103 - 57:[-2.(2x-1)2 – (-9)0]= -106
b) -2x + 3.{12 - 2[3x - (20 + 2x) - 4x] + 1}= 45
Tìm số nguyên x biết
a.-5.(-x+7)-3.(-x-5)=-4.(12-x)+48
b.-2.(15-3x)-4.(-7x+8)=-5-9.(-2x+1)
c.7.(-x-7)-5.(-x-3)=12.(3-x)
d.5.(-3x-7)-4.(-2x-11)=7.(4x+10)+9
f.-2.(x+3)-15=3.(4+2x)+7
giúp tớ nhé tớ đang cần gấp help me
x + 12 =(-5)-x
x + 5 = 10 - x
12-x=x+1
14+4x=3x-20
2x(x-1)+3(x-2)=x-4
3x(4-x)-2x(x-1)=x+20
4x(2x+7-3x(3x-2)=24
Helpppp ;;;v;;;
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 x
a) 3x - 10 = 2x + 13
b) x + 12 = -5 - x
c) x + 5 - 10 - x
d) 6x + 2 ^ 3 = 2x - 12
e) 12 - x = x + 1
f) 14 - 4x = 3x + 20
B) 17X - ( -16X - 37 ) + 2x + 43
C) -2x -3.( x-17) = 34 -2 (-2x +25)
D) 17x+ 3. ( -16x -37) = 2x +43 -4x
E) {- 3x +2. [45 - x-3 (3x + 7) - 2x] + 4x} =55
F) -103 - 57 : [ -2 ( 2x -1 )2 - ( -9 )0 ] - 106
G) -2x + 3. { 12-2 [ 3x - ( 20 + 2x ) - 4x ] + 1} = 45
tìm số nguyên x biet
-2.(x+6)+6.(x-10)=8
x+5=20-(12-7)
(3x-9).(2x+6)=0
(2x+1).(3-x)=0
