Answer:

a

Step-by-step explanation:

14x+42=35

14×=35-42

14× = -7

×= -7/14

×= -1/2

Answer:

A

Step-by-step explanation:

Given f(x) = 14x + 42 and f(x) = 35, then equate right sides, that is

14x + 42 = 35 ( subtract 42 from both sides )

14x = - 7 ( divide both sides by 14 )

x = - [tex]\frac{7}{14}[/tex] = - [tex]\frac{1}{2}[/tex] → A
