x+12=20+12
x+12=32
x=32-12
x=20
tk mk mk tk lại
(^_^)
x + 12 = 20 + 12
x + 12 = 32
x = 32 - 12
x = 20
Tìm x:
x + 12 = 20 + 12
x + 12 = 32
x = 32 - 12
x = 20
Vậy x=20
x + 12 = 20 + 12
x + 12 = 32
x = 32 - 12
x = 20
x + 12 = 20 + 12
x + 12 = 32
x = 32 - 12
x = 20
Vậy x = 20
x + 20 = 20 + 12
x + 20 = 32
x = 32 - 20
x = 12
x + 12 = 20 + 12
x + 12 = 32
x = 32 - 12
x = 20
Vậy x = 20
Chúc bn hok tốt , tk mk nha !
\(x+12=20+12\)
\(x+12=32\)
\(x=32-12\)
\(x=20\)
x + 12 = 20 + 12
x + 12 = 32
x = 32 - 12
x = 20
k mk nha
X + 12 = 20 + 12
x + 12 = 32
x = 32 - 12
x =20
x + 12 = 20 +12
x +12 = 32
x = 32 - 12
x =20
k nhé!
x+12=20+12
x+12=32
x=32-12
x=10
Vậy x=10
