k mk nha
câu 1:
3636:(12*x-91)= 36
12*x-91=3636:36
12*x-91=101
12*x =101 + 91
12*x =192
x =192 : 12
x =16
câu 2:
(x:23+45)*67=8911
x:23+45 =8911 : 67
x:23+45 =133
x:23 =133 - 45
x:23 = 88
x = 88*23
x =2024
a ) \(\left(x+74\right)-318=200\)
\(\left(x+74\right)=200+318\)
\(x+74=518\)
\(x=518-74\)
\(x=444\)
Vậy \(x=444\)
b ) \(3636:\left(12x-91\right)=36\)
\(\left(12x-91\right)=3636:36\)
\(12x-91=101\)
\(12x=101+91\)
\(12.x=192\)
\(x=192:12\)
\(x=16\)
Vậy \(x=16\)
c ) \(\left(x:23+45\right).67=8911\)
\(\left(x:23+45\right)=8911:67\)
\(x:23+45=133\)
\(x:23=133-45\)
\(x:23=88\)
\(x=88.23\)
\(x=2024\)
Vậy \(x=2024\)
Chúc bạn học tốt !!!
