Answer:

n = -11

Explanation:

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away -4 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

n - 4 = -15

→ Add -4 to both sides to isolate n

n = -11

→ We can substitute n = -11 back into the equation to check the value of n is correct, if we get -15 on both sides then our value of n is correct

n - 4 = -15

-11 - 4 = -15

-15 = -15

So n = -11 is correct

n - 4 = -15

Answer:

n= -11

Explanation:

if you want the value of n then the value can be calculated as

n - 4= -15

n = -15+4

n = - 11

n is the any number that can be any value which is just an assumption. in some cases you can also assume x as a number if you don't know the exact value
