a) \(x:\left[\left(1800+600\right):30\right]=560:1515+35\)
\(x:\left[\left(1800+600\right):30\right]=\dfrac{112}{303}+35\)
\(x:\left[\left(1800+600\right):30\right]=\dfrac{10717}{303}\)
\(x:\left[2400:30\right]=\dfrac{10717}{303}\)
\(x:80=\dfrac{10717}{303}\)
\(x=\dfrac{10717}{303}.80\)
\(x=\dfrac{857360}{303}\)
x:[(1800+600):30]=560:(315-35)
[(250-25):15]:x=(450-60):130
1) Tìm x , biết
a) x : [ ( 1800 + 600 ) : 30 ] = 560 : ( 315 - 35 )
b) [ ( 250 - 25 ) : 5 ] : x = ( 450 - 60 ) : 30
giải giúp mik nha
Tìm biết:

Bai 1 : Tinh a) 24 - (-15) - 2 b) (-85) + 10 - (-85) - 50 c) 71 - (-30) - (+18) + (-30)
d) -(30) - (+37) + (+37) + (-85) e) (35-815) - (795-65) g) (2002-79+15) + (-79+15)
h) -(515-80+91) - (2003+80-91)
Bai 2: Tim x,biet a) 25 - (30+x) = x - (27-8) b) (x-12) - 15 = (20-17) - (18+x) c) 15 - x = 7 - (-2) d) x - 35 = (-12) - 3 e) I5-xI - 26 = - 15
