Question

( \(3^2\)- 2 ) ( x - 12 ) + 35 = \(5^2\) + 279 : \(3^2\)

Answer 1

( 3² - 2 ) ( x - 12 ) + 35 = 5² + 279 : 3²

( 3² - 2 ) ( x - 12 ) + 35 = 25 + 279 : 9 

( 3² - 2 ) ( x - 12 ) + 35 = 56

3² - 2 ( x - 12 ) = 56 - 35

9 - 2 ( x - 12 ) = 21

2 ( x - 12 ) = 9 - 21

2 ( x - 12 ) = -12

x - 12 = - 12 : 2 

x - 12 = - 6 

x = - 6 + 12 

x = 6

Answer 3

( 3² - 2 ) ( x - 12 ) + 35 = 5² + 279 : 3²

( 3² - 2 ) ( x - 12 ) + 35 = 25 + 279 : 9 

( 3² - 2 ) ( x - 12 ) + 35 = 56

3² - 2 ( x - 12 ) = 56 - 35

9 - 2 ( x - 12 ) = 21

2 ( x - 12 ) = 9 - 21

2 ( x - 12 ) = -12

x - 12 = - 12 : 2 

x - 12 = - 6 

x = - 6 + 12 

x = 6

Answer 4

( 3² - 2 ) ( x - 12 ) + 35 = 5² + 279 : 3²

( 3² - 2 ) ( x - 12 ) + 35 = 25 + 279 : 9 

( 3² - 2 ) ( x - 12 ) + 35 = 56

3² - 2 ( x - 12 ) = 56 - 35

9 - 2 ( x - 12 ) = 21

2 ( x - 12 ) = 9 - 21

2 ( x - 12 ) = -12

x - 12 = - 12 : 2 

x - 12 = - 6 

x = - 6 + 12 

x = 6

Answer 5

( 3² - 2 ) ( x - 12 ) + 35 = 5² + 279 : 3²

( 3² - 2 ) ( x - 12 ) + 35 = 25 + 279 : 9 

3² - 2 ( x - 12 ) = 56 - 35

9 - 2 ( x - 12 ) = 21

2 ( x - 12 ) = -12

x - 12 = - 12 : 2 

x = - 6 + 12 

x = 6
