Question

2(x-3)=12 me ajudem por favor

Answer 1

2(x - 3 ) = 12

2x - 6 = 12

2x = 12 + 6

2x = 18

Resp: x = 9

Answer 2

2 (- 3 + x) = 12
(- 3. 2   + x. 2) = 12
( - 6  + 2x) = 12
- 6 + 2x = 12
- 6 + 6 + 2x = 12 + 6
-6 + 6 - 0
0 + 2x  - 12 + 6 
2x = 12 + 6
12 + 6 = 18
2x = 12 + 6 
12+ 6 = 18
2x - 18
x = 18/2
x = 9
