-9n + 5 = -67 for n?


Addition Property of Equality

Subtraction Property of Equality

Multiplication Property of Equality

Division Property of Equality

Answer 1

idk what it's called but i do know how to solve for n. xP

Answer 2

if i show you how, maybe you could look for the definition of each property.

-9n + 5 = -6

1st.. transfer -9n to right side.

5 = -6 + 9n

2nd.. transfer -6 to left side.

5 + 6 = 9n

3rd.. divide both sides by 9 to eliminate 9 in 9n..

11/9 = n or n = 11/9

Answer 3

hbaldon's 1st.. transfer, uses the fact that we can add something to both sides of the equation and this will have the same solution as the solution to the original

hbaldron has added 9n to both sides
