a)X*6=1524
X=1524:6
X=254
b)56:X=8
X=56:8
X=7
tk minh nha
a) 6X = 3048 : 2
6X = 1524
X = 1524 : 6
X = 254
b) 56 : X = 1326 - 1318
56 : X = 8
X = 56 : 8
X = 8
a , x . 6 = 1524
x = 1524 : 6
x= 254
b , 56 :x = 8
x = 56 : 8
x = 7
\(a,x\times6=3048:2\)
\(x\times6=1524\)
\(x=1524:6\)
\(x=254\)
\(b,56:x=1326-1318\)
\(56:x=8\)
\(x=56:8\)
\(x=7\)
