Penyelesaian dari 1/2(x-6)=2+4/3xadalah x=p.Nilai dari 2p-1 adalah...

[tex] \frac{1}{2} (x - 6) = 2 + \frac{4}{3} x \\ \frac{1}{2} x - 3 = 2 + \frac{4}{3} x \\ 3x - 18 = 12 + 8x \\ 3x - 8x = 12 + 18 \\ - 5x = 30 \\ x = - \frac{30}{5} \\ x = -6 [/tex]

Maka nilai 2p - 1 :
= 2(-6) - 1
= -12 - 1
= -13

1/2(x - 6) = 2 + 4/3x
1/2x - 3 = 2 + 4/3x
1/2x - 4/3x = 2 + 3
3/6x - 8/6x = 5
-5/6x = 5
x = 5 : (-5/6)
x = 5 x 6/-5
x = 30/-5
x = -6
x = p = -6
2p - 1 
= 2(-6) - 1
= -12 - 1 = -13
