1. Simplify on the right side

[tex]3n - 5 = -48 - 40n[/tex]

2. Add '40n' to both sides

[tex]3n + 40n - 5 = -48 - 40n + 40n[/tex]

[tex]43n - 5 = -48[/tex]

3. Add '5' to both sides

[tex]43n - 5 + 5 = -48 + 5[/tex]

[tex]43n = -43[/tex]

4. Divide '43' to both sides

[tex] \frac{43n}{43} = \frac{-43}{43} [/tex]

[tex]n = -1[/tex]
