Question

1. -28 = -3n + 5

what is n??
2.5−n3=−4

Answer 1

11

Explanation:

Answer 2

1.

n=11

2.

`n = \sqrt[3]{9}`

Explanation:

Question 1:

The given equation is:

`- 28 = - 3n + 5`

Subtract 5 from both sides:

`- 28 - 5 = - 3n`

`- 33 = - 3n`

Divide boy sides by:

-3

`n = ( - 33)/( - 3) = 11`

Question 2:

The given expresion is :

`5 - {n}^(3) = - 4`

Subtract 5 from both sides

`- {n}^(3)= - 4 - 5`

This implies that;

`- {n}^(3)= - 9`

`{n}^(3)= 9`

`n = \sqrt[3]{9}`
