Question

ƒ(x) = 18x + 8, find x when ƒ(x) = 14.

Answer 1

Answer:

x=1/3

Step-by-step explanation:

ƒ(x) = 18x + 8,

ƒ(x) = 14

then

18x+8=14

18x=14-8

18x=6

x=6/18

x=1/3

Answer 2

Answer:

x = 1/3

Step-by-step explanation:

ƒ(x) = 18x + 8,

ƒ(x) = 14

14 = 18x+8

Subtract 8 from each side

14-8 = 18x+8-8

6 = 18x

Divide each side by 18

6/18 = 18x/18

1/3 =x
