Ta có : \(\dfrac{x+518}{6}+60=253+15\times4\)
\(\Leftrightarrow\dfrac{x+518}{6}=253\)
\(\Leftrightarrow x+518=1518\)
<=> x = 1000
Vậy x = 1000 là nghiệm phương trình
X+518/6+60=313
X+518/6=313-60
X+518/6=253
X+518=253x6
X+518=1518
X=1518=518
X=1000
\(\dfrac{x+518}{6}+60=253+15x4\)
\(\dfrac{x+518}{6}=253+5x4-60\)
\(\dfrac{x+518}{6}=253\)
\(x+518=1518\)
\(x=1000\)
Vậy x =1000
