x=10,17(làm tròn nha)
k mik nha
học tốt
^_^
\(575-6.\left(x+10\right)=454\)
\(\Rightarrow6.\left(x+10\right)=575-454=121\)
\(\Rightarrow x+10=\frac{121}{6}\)
\(\Rightarrow x=\frac{121}{6}-10=\frac{121}{6}-\frac{60}{6}\)
\(\Rightarrow x=\frac{61}{6}\)
575 - 6(x + 10) = 454
<=>575 - 6x + 60 = 454
<=> -6x = 454 - 575 -60
<=> -6x = -181
<=> x = -181 : (-6)
<=> x = 181/6
Vậy x = 181/6
