Tolong dibantu ya pakai caranya makasi

2) g(3) = 3m + 5 = 2
3m = 2 – 5
3m = – 3
m = – 1

3) n(-2) = – 2a + 3 = 2
– 2a = 2 – 3
– 2a = – 1
a = ½
n(x) = ½x + 3
n(8) = ½ . 8 + 3 = 4 + 3 = 7
(gak ada di pilihan jwbnya)

1) f(a) = (2a – 5) / (a + 3) = – 5
2a – 5 = – 5(a + 3)
2a – 5 = – 5a – 15
2a + 5a = – 15 + 5
7a = – 10
a = – 10/7
