Question

\(2x-3^2=36\)

Answer 1

\(\Rightarrow2x-9=36\Leftrightarrow2x=45\Leftrightarrow x=\dfrac{45}{2}\)

Answer 2

2x - 3² = 36

2x - 9 = 36

2x = 36 + 9

2x = 45

x = 45 : 2

x = 45/2.

Answer 3

2x - 3² = 36

2x = 36 + 9

x = 45 : 2

x = 45/2.

Answer 4

`2x - 3^2 = 36`

`=> 2x - 9 = 36`

`=> 2x      = 36 + 9`

`=> 2x     = 45`

`=>  x      = 45 : 2`

`=> x      = 22,5` hay `45/2`
