\(115-x\div5=20\)
\(x\div5=115-20\)
\(x\div5=95\)
\(x=95\times5\)
\(x=475\)
115 - x : 5 = 20
x : 5 = 115 - 20
x : 5 = 95
x = 95 x 5
x = 475
Hok tốt
\(115-x:5=20\)
\(< =>115-\frac{x}{5}=20\)
\(< =>\frac{x}{5}=115-20=95\)
\(< =>x=95.5=475\)
115-x:5=20
x:5=115-20
x:5=95
x=95×5
x=475
vậy x=475
\(115-x:5=20\)
\(x:5=115-20\)
\(x:5=95\)
\(x=95:5\)
\(x=19\)
Vậy : x = 19
115 - x : 5 = 20
x : 5 = 115 - 20
x : 5 = 95
x = 95 x 5
x = 475
\(115-x\div5=20\)
\(x\div5=115-20\)
\(x\div5=95\)
\(x=95\times5=475\)
