Question

24+3 (5 -x) = 27

Answer 1

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

Answer 2

\(24+3\left(5-x\right)=27\)

\(\Rightarrow3\left(5-x\right)=27-24\)

\(\Rightarrow3\left(5-x\right)=3\)

\(\Rightarrow5-x=\dfrac{3}{3}\)

\(\Rightarrow5-x=1\)

\(\Rightarrow x=5-1\)

\(\Rightarrow x=4\)

Answer 3

`24 +3(5-x)=27`

`<=> 24 + 15-3x=27`

`<=> 39-3x=27`

`<=> 3x=12`

`<=> x=12:3`

`<=> x=4`

Vậy `x=4`.
