Can someone help me?

Rasek [7]

Step-by-step explanation:

$given \: - 5n = 4m$

making m the subject first by dividing through by 4

$\frac{ - 5}{n} = \frac{4m}{4}$

$m = \frac{ - 5n}{4}$

from the question, given n = -1 ,0 ,1

so when n= -1

$m = \frac{ - 5( - 1)}{4}$

$m = \frac{5}{4}$

when n=0

$m = \frac{ - 5(0)}{4}$

$m = \frac{0}{4}$

$m = 0$

when n=1

$m = \frac{ - 5(1)}{4}$

$m = \frac{ - 5}{4}$
