(X+0.75)x4-8=205,8
(X+0.75) x 4 =205.8+8
(X+0.75) x 4 =213,8
(X+0.75) =213.8 : 4
X+0.75=53.45
X=53.45-0.75
X=52.7
(x+0,25)×4=205,8+8
(x+0,25)×4=213,8
(x+0,25)=213,8:4
(x+0,25)=53,45
x=53,45-0,25
x=53,2
\((x+0,75)\times4-8=205,8\)
\((x+0,75)\times4\) \(=205,8+8\)
\((x+0,75)\times4\) \(=213,8\)
\(x+0,75\) \(=53,45\)
\(x\) \(=53,45-0,75\)
\(x\) \(=52,7\)
Học tốt , nhớ kết bạn nha
\(\left(x+0,75\right)x4-8=205,8\)
\(\Leftrightarrow\left(x+0,75\right)\times4=213,8\)
\(\Leftrightarrow x+0,75=53,45\)
\(\Leftrightarrow x=52,7\)
Vậy : x = 52,7
