tolong jawab menggunakan cara

1/2 (x - 6) = 2 + 4/3 x
1/2 x - 6/2 = 6/3 + 4/3 x
1/2 x - 4/3 x = 6/3 + 6/2
3/6 x - 8/6 = 12/6 + 18/6
-5/6 x = 30/6
-5/6 x = 5
x = 5 / -5/6
= 5 x 6/-5
= 30/-5
= -6

x = p -> p = -6

2p - 1 =
2 (-6) - 1 =
-12 - 1 =
-13 (A)

Semoga membantu:)

1/2 (x - 6) = 2 + 4/3x
   1/2x - 3 = 2 + 4/3x
---------------------------- dikali 6
    3x - 18 = 12 + 8x
    3x - 8x  = 12 + 18
           -5x = 30
              x = 30/-5
              x = -6
x = p

2p - 1
= 2(-6) - 1
= -12 - 1
= -13
