Question

Tolong bantu jawab y kak dari nomber 14 sampai 18 .Isi caranya y kak.....(poinnya banyak loh...:v)

Answer 1

Jadi itu jawabannya No 18 aku gak sempat kerjain

Answer 2

14.
4x + 18 = 6 - 2x
4x + 2x = 6 - 18
6x = -12
x = -2

15.
4(2y - 3) = 4y + 10
8y - 12 = 4y + 10
8y - 4y = 10 + 12
4y = 22
y = 22/4
y = 5 ½

16.
4(2y + 3) - 2y = 3(4y + 3)
8y + 12 - 2y = 12y + 9
6y - 12y = 9 -12
-6y = -3
y = -3/-6
y = ½
nilai y + 5 = 5 ½

17.
⅔(2y - 3) = ½(4y + 2)
4(2y - 3) = 3(4y + 2)
8y - 12 = 12y + 6
8y - 12y = 6 + 12
-4y = 18
y = -18/4
y = -4½

18.
(2y - 5)/4 + 7/14 = (4y -1)/3
3(2y - 5) + 6 = 4(4y - 1)
6y - 15 + 6 = 16y - 4
6y - 16y = -4 + 9
- 10y = 5
y = -5/10
y = -½
