Jika 2(x - y) = 6, maka nilai dari 3(y - x) adalah ....

[tex]2(x - y) = 6[/tex]

[tex]x - y = \frac{6}{2} \\ [/tex]

[tex]x - y = 3[/tex]

[tex] - y + x = 3[/tex]

[tex] - (y - x) = 3[/tex]

Kalikan kedua ruas sama dengan x (-1)

[tex] ( - 1)( - 1)(y - x) = 3( - 1)[/tex]

[tex](y - x) = - 3[/tex]

sehingga;

[tex] = 3(y - x)[/tex]

[tex] = 3( - 3)[/tex]

[tex] = - 9[/tex]

Jadi, nilai dari 3(y - x) adalah -9.

SOAL 1

2(x - y) = 6

(x - y) = 6 ÷ 2

(x - y) = 3

(-y + x) = 3 [ × - 1 ]

(y - x) = -3

3(y - x)

= 3(-3)

= 3 × (-3)

= -9
