Question

30 - (2x - 5) = 3⁵ : 3²

Answer 1

\(30-\left(2x-5\right)=3^3\)

\(2x-5=30-27\)

\(2x-5=3\)

\(2x=8\)

\(x=4\)

Answer 2

=>30-(2x-5)=27

=>2x-5=3

=>2x=8

=>x=4

Answer 3

30-(2x-5)=3⁵ :3²

2x-5=30-3^5-2

2x-5=30-3³

2x-5=30-27

2x-5=3

2x=3+5

x=8:2

x=4 

Vậy x=4

 

Answer 4

30 − ( 2x − 5 ) = 3^3

2x − 5 = 30 − 27

2x − 5 = 3

2x = 8

x = 4

Vậy x = 4
