tolong bantu ya kak... no. 3

5/6 (x+2) = ½x - 2
= 5/6x + 10/6 = ½x - 2
* ½x nya pindahin ke kiri= 5/6 - ½ = 5/6 - 3/6 = 2/6 = 1/3x
=⅓x + 10/6 = -2

= ⅓x= -2 - 10/6 = -2/1 - 10/6 = -12/6 - 10/6 = -22/6


⅓x = -22/6
x = -22/6 : ⅓x = -22/6 x 3/1x = -66/6 = -11

ditanya : x - 2 ? = -11 - 2 = -13

kalau masih bingung, nanti saya usahain pake gambar :)
