Hello!
Answer:
n=-9
*The answer must have a negative sign.*
Step-by-step explanation:
First, you subtract by 7 from both sides of an equation.
[tex]7+2n-7=-11-7[/tex]
Then, you simplify.
[tex]2n=-18[/tex]
Next, you divide by 2 from both sides of an equation.
[tex]\frac{2n}{2}=\frac{-18}{2}[/tex]
And finally, simplify and solve. You can also dividing into the groups.
[tex]18/2=9[/tex]
[tex]n=-9[/tex]
Hope this helps!
