x + 50 = 100
x = 100 - 50
x = 50
K mk mk k lại
x + 50 = 20 x 5
x + 50 = 100
x = 100 - 50
x = 20
k mk nha
\(x+50=20\times5\)
\(x+50=100\)
\(x=100-50\)
\(x=50\)
x +50 = 100
x = 100 - 50
x = 50
mik nha mik bạn rồi
x + 50 = 100
x = 100 - 50
x = 50
X + 50 = 20 x 5
X + 50 = 100
X = 100 - 50
X = 50
Vậy X = 50
Ta co:x+50=20x5
<=>x+50=100
<=>x=100-50=50
Vay x=50
x + 50 = 20 x 5
x + 50 = 100
x = 100 - 50
x = 50
