Opsi a.

__________

[tex]2(3p - 6) = 3p - 9[/tex]

[tex]6p - 12 = 3p - 9[/tex]

[tex]6p - 3p = - 9 + 12[/tex]

[tex]3p = 3[/tex]

[tex]p = \frac{ \cancel3}{ \cancel3} \\ [/tex]

[tex]p = \frac{1}{1} \\ [/tex]

[tex]p = 1[/tex]

Jawaban : a. 1

Penjelasan :

2(3p - 6) = 3p - 9

2 × 3p - 2 × 6

6p - 2 × 6

= 6p - 12

6p - 12 = 3p - 9

6p - 12 - 3p = 3p - 9 - 3p

6p - 12 - 3p = - 9

6p - 3p = - 9 + 12

3p = - 9 + 12

3p = 3

3p ÷ 3 = 3÷3

p = 3÷3

p = 1
