x - 105:15 = 45
x - 7 = 45
x = 45 + 7
x = 52
x-105:15=45
x-105 =45:15
x-105 =3
x = 3+105
x = 108
x-105:15=45
<=>x-105=675
<=>x=570
Vậy ...
k mik nhé
x-105=45.15
x-105=675
x =675+105
x =780
Vậy x=180
k cj nhé
x - 105 : 15 = 45
<=> x - 7 = 45
<=> x = 45 + 7
<=> x = 52
Vậy x = 52
!!!
Mik nhầm
x-105:15=45
<=>x-7=45
<=>x=52
Vậy...
\(x-105:15=45\)
\(\Leftrightarrow x-7=45\)
\(\Rightarrow x=52\)
P/s tham khảo nha
x - 105:15 = 45
x - 7 = 45
x = 45 + 7
x = 52
Vậy x = 52
