Answer:
[tex]n=-0.24[/tex]
Step-by-step explanation:
[tex]3\left(-0.4n-0.7\right)=-3.2n-2.58[/tex]
Use distributive property.
[tex]-1.2n-2.1=-3.2n-2.58[/tex]
[tex]-1.2n-2.1+2.1=-3.2n-2.58+2.1[/tex]
[tex]-1.2n=-3.2n-0.48[/tex]
[tex]-1.2n+3.2n=-3.2n-0.48+3.2n[/tex]
[tex]2n=-0.48[/tex]
[tex]\frac{2n}{2}=\frac{-0.48}{2}[/tex]
[tex]n=-0.24[/tex]
