4-(27-3)=x-(13-4)
x-(13-4)=4-(27-3)
x-9=4-24
x-9=-20
x=-20+9
x=-11
Vậy x=-11
4-(27-3)=x-(13-4)
4-27+3=x-13+4
-20=x-9
x=11
Vậy x=11
Tìm số nguyên \(x\), biết : \(4-\left(27-3\right)=x-\left(13-4\right)\)
1) cho a,b thuộc tập hợp Z tìm số nguyên x,biết:
a) a + x = 5 b) a - x = 2 c) a + x = b d) a - x =b
2) tìm số nguyên x ,biết: 4 - ( 27 - 3 ) = x -( 13 - 4 )

45-(-x+1)+50=2x-5+37
\(\left(x-2\right)^3+\frac{8}{27}=0\)
\(4\frac{1}{3}:\frac{x}{4}=6:0,3\)
(0,25-30%x).\(\frac{1}{3}-\frac{1}{4}=5\frac{1}{6}\)
\(\frac{x-2}{\frac{-2}{9}}=\frac{-2}{x-2}\)
Tìm x sao cho:
a) 18 - x = 58 - (-30)
b) x - 27 = (-43) - 9
c) 169 - (x + 4) = 69
d) (5x + 3) - (-24 + 4) = 33
e) 225 - (5x + 10) : 25 + 5 = -(-20)
27.(13-16)-16.(13-27)
Tìm số nguyên x, biết:
a) x - 73 = (57 - x) - 467
b) -(x - 3 - 84) = 70 - (-27) - 115
c) 231 - x + 62 = 46 + (x - 21)
d) -18 + x = -63 - (-33)
e) (x - 153) - (48 - 193) = 1 - 2 - 3 - 4
a, 20 - ( -40 ) + 10 b, -21 + ( -13 ) - 4 c, ( 3 - 23 ) - ( 4 - 10 ) d, ( -8 + 15 ) - ( -6 - 20 )
