di ketahui persamaan garis g:2x-3y-14=0 a. jika garis melalui titik (1, a), tentukan nilai a
![]()
2x²-3y-14=0
3y=-2x²+14
masukkan(1,a)
3a=-2+14
3a=12
a=3
[tex]2x - 3y - 14 = 0\\ 2x - 3y = 14 \\ 2(1) - 3y = 14 \\ 2 - 3y = 14 \\ 2 - 14 = 3y \\ - 12 = 3y \\ y = \frac{ - 12}{3} \\ y = - 4 \\ nilai \: a = - 4[/tex]
