-4n-40=-2(7n+5)<br> please show work
Grace [21]

Answer:

n=3

Step-by-step explanation:

-4n-40=-2(7n+5)

Distribute the -2

-4n -40 = -14n -10

Add 14n to each side

-4n+14n -40 = -14n +14n-10

10n -40 = -10

Add 40 to each side

10n -40+40 = -10+40

10n = 30

Divide each side by 10

10n/10=30/10

n =3
