Answer:
[tex]c=-1.12[/tex]
Step-by-step explanation:
[tex]7.2\left(9c+1\right)=-65.376[/tex]
[tex]\frac{7.2\left(9c+1\right)}{7.2}=\frac{-65.376}{7.2}[/tex]
[tex]9c+1=-\frac{227}{25}[/tex]
[tex]9c+1-1=-\frac{227}{25}-1[/tex]
[tex]9c=-\frac{252}{25}[/tex]
[tex]\frac{9c}{9}=\frac{-\frac{252}{25}}{9}[/tex]
[tex]c=-\frac{28}{25}[/tex]
[tex]c=-1.12[/tex]
