7 x X = 700-224
7x X = 476
X=476:7
Vậy X = 68
mk đầu tiên
\(700-7\times x=224\)
\(7\times x=700-224\)
\(7\times x=476\)
\(x=476\div7\)
\(x=68\)
Vậy x = 68
\(700-7\times x=224\)
\(7\times x=700-224\)
\(7\times x=476\)
\(x=476\div7\)
\(x=68\)
Vậy x = 68
700-7.x=224
7.x=70-224
7.x=476
x=476:7
x=68
vAY X= 68
700 -7xX =224
7xX=700-224
7xX=476
X=476:7
X=68
Vậy X=68
