24 + 3 x (5 - x) = 27
27 x (5 - x) = 27
5 - x = 27 : 27
5 - x = 1
x = 5 - 1
x = 4
24 + 3. ( 5 - x ) = 27
3 . ( 5 - x ) = 27 - 24
3 . ( 5 - x ) = 3
5 - x = 3 : 3
5 - x = 1
x = 5 - 1
x = 4
24+3*(5-x)=27
3*(5-x)=3
5-x=1
x=4
24 + 3*(5-x) = 27
3*(5-x) = 27 - 24
3*(5-x) = 3
(5-x) = 3/3
5-x = 1
x= 5-1
x=4
vậy x = 4
24+3.(5-x)=27
3.(5-x) =27-24
3.(5-x) =3
5-x =3:3
5-x =1
x =5-1
x =4
\(\Leftrightarrow\)3*(5-x)=3
\(\Leftrightarrow\)5-x=1
\(\Leftrightarrow\)x=4
24+3*(5-x)=27
3*(5-x ) = 3
5 - x = 1
x = 4
\(24+3.\left(5-x\right)=27\)
\(3.\left(5-x\right)=27-24\)
\(3.\left(5-x\right)=3\)
\(5-x=3:3\)
\(5-x=1\)
\(x=5-1\)
\(x=4\)
