1. 5-25=3x-4 => -20=3x-4 => -16=3x => x= -16/3
2. 1-2x=3-2x-2 => 1=3-2 => 1=1 => x=R

Answer:

f = - $\frac{19}{7}$

Step-by-step explanation:

Given f varies directly with m then the equation relating them is

f = km ← k is the constant of variation

To find k use the condition f = - 19 when m = 14

- 19 = 14k ( divide both sides by 14 )

- $\frac{19}{14}$ = k

f = - $\frac{19}{14}$ m ← equation of variation

When m = 2 , then

f = - $\frac{19}{14}$ × 2 = - $\frac{19}{7}$
