X x 20 = 500 x 2
X x 20 = 1000
X = 1000 : 20
X = 50
k mk nha
X x 20 = 500 x 2
X x 20 = 1000
X = 1000 : 20
X = 500
X x 20 = 500 x 2
X x 20 = 1000
X = 1000 : 20
X = 50
nhé !
\(X\times20=500\times2\)
\(X\times20=1000\)
\(X=1000:20\)
\(X=50\)
\(X\times20=500\times2\)
\(X\times20=1000\)
\(X=1000:20\)
\(X=50\)
\(X\times20=500\times2\)
\(X\times20=1000\)
\(X=1000:20\)
\(X=50\)
x . 20 = 500 x 2
x . 20 = 1000
x = 1000 : 20
x = 50
20x=500.2
20x=1000
x=1000/20
x=50
Vậy x=50
