Answer 1

x+ 2 + x+ 4 + x +6 + x + 8 + x + 10 + x + 12 = 192

6x +  2+ 4 + 6 + 8 + 10 + 12  = 192

6x+ 42 = 192 

6x= 192 - 42

6x= 150

x = 150 : 6

x= 25

 

Answer 2

x+2+x+4+x+6+x+8+x+10+x+12= 192

<=> 6x + 42 = 192

<=> 6x = 150

<=> x = 25

Answer 3

x+ 2 + x+ 4 + x +6 + x + 8 + x + 10 + x + 12 = 192

6x +  2+ 4 + 6 + 8 + 10 + 12  = 192

6x+ 42 = 192 

6x= 192 - 42

6x= 150

x = 150 : 6

x= 25
