\(x-24=-114+23\)
\(< =>x-24=-101\)
\(< =>x=-101+24\)
\(< =>x=-77\)
Vậy .............
x - 24 = -114 + 13
x - 24 = -101
x = -101 + 24
x = -77
x - 24 = - 114 + 13
x - 24 = - 101
x = - 101 + 24
x = - 77
Vậy x = - 77
\(x-24=-114+23\)
\(< =>x-24=-101\)
\(< =>x=-101+24\)

Vậy .............
x - 24 = -114 + 13
x - 24 = -101
x = -101 + 24
x = -77
x - 24 = - 114 + 13
x - 24 = - 101
x = - 101 + 24
x = - 77
Vậy x = - 77
Bài 1: Tìm x, biết:
a) -15 + (53 – x) = 13 – (4 – 10)
b) 11 – (25 – x + 11) = - (45 – 7)
c) 23 + (63 – 7) = 5 – (23 - x)
d) 114 – (72 – x) = 24 – (25 – 43)
Tìm x, biết:
a ) x − 1 2 = 1 3 ; b ) 5 7 − x = − 9 21 c ) − x − 5 7 = 1 14 ; d ) − 5 6 − x = 7 12 + − 1 3
19,96 +4,19 -24 ,15 :(:1/4-1/4)=23,15
252/x=84/97
x-2/255=114/153
1722:{5740:[1470-(125+75.x)]}-114=13
2193:{[(2223-18x):135-7]+123}+1989=2006
{[(2x+14):2^2-3]:2}+19=20
3 x 24/13 + 2 x 3/13 = ?
Tính nhanh:
a) 38 + 41 + 117 + 159 + 62
b) 73 + 86 + 968 + 914 + 3032
c) 341 x 67 + 341 x 16 + 659 x 83
d) 42 x 53 + 47 x 156 - 47 x 114
e) (44 x 52 x 60) : (11 x 13 x 15)
3x + 10 = 13 x 7
11x = 114 : 121
3x - 3 x 22 = 32 = 32 + 6
Ai chơi Mini World thì kb với mk nhé
X – ( 13 – X ) = - 24 + ( -7 + X )
x - (13-x) = -24 + (-7 + x)
