tolong cara kerjanya donk? diketahui rumus f(x) = 2x - 5. jika F(K) = -15, maka nilai K adalah...

Kelas 8 Matematika
Bab Fungsi

f(x) = 2x - 5

f(k) = -15
2k - 5 = -15
2k = -15 + 5
k = -10/2
k = -5

————————————————————
f(x) = 2x - 5

f(k) = - 15
2(k) - 5 = - 15
2(k) = - 15 + 5
2(k) = - 10
k = - 10 / 2
k = - 5 ✔️
