1. Diketahui fungsi F dengan rumus F (X) = 5 - 7X , jika F (A) = 30 , Tentukan nilai A ! 2. Diketahui fungsi F dengan rumus F (X) = 5X - 2 , jika F (A) = 13 , T

1. F (X) = 5 - 7X
F (A) = 5 - 7A

F (A) = 30
F (A) = 5 - 7A = 30
- 7A = 30 -5
- 7A = 25
A = 25/-7

2. F (X) = 5X - 2
F (A) = 5A - 2

F (A) = 13
F (A) = 5A - 2 = 13
5A = 13 + 2
A = 25/5 = 5

Semoga membantu yaa:)
