4 - (27-3) = x - (13-4).
4 - 24 = x - 9 hay x -9 = 4 - 24
x - 9 = -20
x = -20 + 9
x = -11
4 - (27-3) = x - (13-4).
4 - 24 = x - 9
x - 9 = - 20
x = -11
4 - (27-3) = x - (13-4).
4 - 24 = x - 9
x - 9 = - 20
x = -11
tim so nguyen x biet 4-(27-30) = x (13-4)
tim so nguyen x biet rang 13/3.(1/6-1/2)<x<2/3.(1/3-1/2/-3/4)
a) tim gia tri nho nhat cua bieu thuc : A = | 1-x | + 8
b) tim cac so nguyen x biet 13 la boi cua x - 4
c) tim so nguyen x sao cho ( x + 5 ) chia het cho ( x + 3 )
giup minh voi! minh can gap gap gap.....
Tim cac cap so nguyen x;y biet : (2x-1)*(y-4)=-13
giup minh voi mai minh nop bai roi : tim cac so nguyen x biet 13 la boi cua x-4
Tim so nguyen x biet |5×x—3|< hoac = 13
Tim so nguyen x de A la so nguyen, biet: A=13:(x-2)
1,tim cac so nguyen x,y biet: -2/x=y/3 va x<0<y
2, Tim cac so nguyen x,y biet:x-3/y-2=3/2 va x-y=4
Tim so nguyen x, biet: -2 . (-x - 5) + 28 = 20 - 3 . (x + 4)
