\(6X+70=575-445\)
\(6X+70=130\)
\(6X=130-70\)
\(6X=60\)
\(X=60:6=10\)
\(575-\left(6x+70\right)=445\)
\(6x+70=575-445\)
\(6x=130-70\)
\(6x=60\)
\(x=\frac{60}{6}\)
\(x=10\)
Vậy \(x=10\)
575 - ( 6x + 70 ) = 445
=> 6x + 70 = 575 - 445
=> 6x + 70 = 130
=> 6x = 130 - 70
=> 6x = 60
=> x = 60 : 6
=> x = 10
Vậy x = 10

_Chúc bạn học tốt_
575 - [ 6x + 70 ] = 445
6x + 70 = 575 - 445
6x + 70 = 130
6x = 130 - 70
6x = 60
