x - 6:2-(48-24):2:6+3 = 0
x- 3 - 24 :2:6+3=0
x-3-2+3 = 0
x-3-2 = 0+3
x-3-2=3
x-3=3+2
x-3=5
x=5+3
x=8
x - 6 : 2 - ( 48 - 24 ) : 2 : 6 + 3 = 0
x - 6 : 2 - 24 : 2 : 6 + 3 = 0
x - 3 - 12 : 6 + 3 = 0
x - 3 - 2 + 3 = 0
x - 3 - 2 =0-3
x - 3 - 2 =-3
x - 3=-3+2
x - 3=-1
x=-1+3
x=2

a) y - 6 : 2 - (48 - 24 x 2 : 6 - 3) = 0
y - 3 - (48 - 48 : 6 - 3) = 0
y - 3 - (48 - 8 - 3) = 0
y - 3 - 37 = 0
y - ( 3+37) = 0
y - 40 =0
y =0+40
Y =40
b) ( 7x13 - 8x13) : ( 9 2/3 -y) =39
(7+8)x13 : (29/3 - y) =39
15 x 13 : (29/3-y) =39
195 : (29/3 - y) =39
29/3 - y =195 : 39
29/3 - y = 5
y = 29/3 - 5
y = 14/3

x - ( 48 - 24 x 2 : 6 - 3 ) = 0
x = 48 - 24 x 2 : 6 - 3
x = 48 - 48 : 6 - 3
x = 48 - 8 - 3
x = 40 - 3
x = 37
Vậy x = 37
Tham khảo nha !!!

X-6:2-(48-24):2:6=0+3
X-6:2-(48-24):2:6=3
X-6:2-(48-24):2=3x6
X-6:2-(48-24):2=18

X=60+3
X=63
Tính đúng y = 40
