Question

Jika f(x)= 7-2x dan f(y)= -3 maka nilai dari y+2 adalah..
Tolong beserta caranya ya, terimakasih

Answer 1

F(x)= 7 - 2x
7 - 2y = -3
-2y = -3 - 7
-2y = -10
y = 5
Maka, y+2 = 5 + 2 = 7:)))

Answer 2

F(y) = -3

f(x) = 7 - 2x
f(y) = 7 - 2y
-3 = 7 - 2y
2y = 7 + 3
2y = 10
y = 5

y + 2 = 5 + 2 = 7
