2+x:7=10
x:7=10-2
x:7=8
x=8 : 7
x=\(8\over7\)
2+x:7=10
x:7 =10+2
x:7 =12
x =12 * 7
x =84
Ta có :
2 + x : 7 = 10
x : 7 = 10 - 2
x : 7 = 8
x = 8 x 7
x = 56
Vậy x = 56
2 + x : 7 = 10
x : 7 = 10 - 2
x : 7 = 8
x = 8 x 6
x = 56
\(2+x\div7=10\)
\(x\div7=10-2\)
\(x\div7=8\)
\(x=8\times7\)
\(x=56\)
x : 7 = 10 - 2
x : 7 = 8
x = 8 x 7
x = 56
2 + x : 7 = 10
x : 7 = 10 - 2
x : 7 = 8 x 7
x = 56
