Answer:
1.
n=11
2.
[tex]n = \sqrt[3]{9} [/tex]
Step-by-step explanation:
Question 1:
The given equation is:
[tex] - 28 = - 3n + 5[/tex]
Subtract 5 from both sides:
[tex] - 28 - 5 = - 3n[/tex]
[tex] - 33 = - 3n[/tex]
Divide boy sides by:
-3
[tex]n = \frac{ - 33}{ - 3} = 11[/tex]
Question 2:
The given expresion is :
[tex]5 - {n}^{3} = - 4[/tex]
Subtract 5 from both sides
[tex] - {n}^{3}= - 4 - 5[/tex]
This implies that;
[tex]- {n}^{3}= - 9[/tex]
[tex]{n}^{3}= 9[/tex]
[tex]n = \sqrt[3]{9} [/tex]
