575-(6.x+70)=445
6x+70=575-445
6x+70=130
6x=130-70
6x=60
x=60:6
x=10
575 - ( 6 x x + 70) = 445
6 * x + 70 = 575 - 445
6 * x + 70 = 130
6 * x = 130 - 70
6 * x = 60
x = 60 : 6
x = 10
k mik nha mik xin thề sẽ k cho các bn
\(575-\left(6\cdot x+70\right)=445\)
\(60\cdot x+70=575-445\)
\(60\cdot x+70=130\)
\(60\cdot x=130-70\)
\(60\cdot x=60\)
\(x=60:60\)
\(x=1\)
\(575-\left(6\cdot x+70\right)=445\)
\(6\cdot x+70=575-445\)
\(6\cdot x+70=130\)
\(6\cdot x=130-70\)
\(6\cdot x=60\)
\(x=60:6\)
\(x=10\)
575 - ( 6 . x + 70 ) = 445
6x + 70 = 575 - 445
6x + 70 = 130
6x = 130 - 70
6x = 60
x = 60 : 6
x = 10
Vậy x = 10
Ta có :
575 - ( 6 x x + 70) = 445
6 * x + 70 = 575 - 445
6 * x + 70 = 130
6 * x = 130 - 70
6 * x = 60
x = 60 : 6
x = 10
Đáp số : x = 10
Ta có :
575 - ( 6 x x + 70) = 445
6 * x + 70 = 575 - 445
6 * x + 70 = 130
6 * x = 130 - 70
6 * x = 60
x = 60 : 6
x = 10
Đáp số : 10
575-(6.x+70)=455
(6.x+70)=575-455
(6.x+70)=130
6.x =130-70
6.x =60
x =60:6
x =10
Vậy x=10
575 - (6 x X + 70) = 445
6 x X + 70 = 575 - 445
6 x X + 70 = 130
6 x X = 130 - 70
6 x X = 60
X = 60 : 6
X = 10
=> Vậy X = 10
