Answer:
[tex] \boxed{ \bold{ \sf{ \boxed{ p = 3}}}} [/tex]
[tex] \boxed{ \bold{ \sf{ \boxed{n = 1}}}}[/tex]
Step-by-step explanation:
1. [tex] \sf{7p - p = 18}[/tex]
Collect like terms
⇒[tex] \sf{6p = 18}[/tex]
Divide both sides of the equation by 6
⇒[tex] \sf{ \frac{6p}{6} = \frac{18}{6} }[/tex]
Calculate
⇒[tex] \sf{p = 3}[/tex]
2. [tex] \sf{ - 5n - 4n = - 9}[/tex]
Collect like terms
⇒[tex] \sf{ - 9n = - 9}[/tex]
Divide both sides of the equation by -9
⇒[tex] \sf{ \frac{ - 9n}{ - 9} = \frac{ - 9}{ - 9} }[/tex]
Calculate
⇒[tex] \sf{n = 1}[/tex]
Hope I helped!
Best regards!!
