24 & 25 pakai caranya

24.
x + 2 = 3y
1/3x + 2/3 = y

m = koefisien x = 1/3
karena sejajar maka gradiennya sama

(3,2)
y-y1 = m(x-x1)
y-2 =1/3(x-3)
y-2 = 1/3x - 1
3y-6 = x-3
3y-x = 3
-x + 3y = 3
x-3y = -3


25.
16p^2 - 81q^2

gunakan sifat a^2-b^2 = (a+b)(a-b)

maka (4p-9q)(4p+9q)


maaf kalau salah yaa
