7p − p = 18 2) −5n − 4n = −9
Savatey [412]

Answer:

<h3>\boxed{ \bold{ \sf{ \boxed{ p = 3}}}}</h3>

\boxed{ \bold{ \sf{ \boxed{n = 1}}}}

Step-by-step explanation:

1. \sf{7p - p = 18}

Collect like terms

⇒\sf{6p = 18}

Divide both sides of the equation by 6

⇒\sf{ \frac{6p}{6}  =  \frac{18}{6} }

Calculate

⇒\sf{p = 3}

2. \sf{ - 5n - 4n =  - 9}

Collect like terms

⇒\sf{ - 9n =  - 9}

Divide both sides of the equation by -9

⇒\sf{ \frac{ - 9n}{ - 9}  =  \frac{ - 9}{ - 9} }

Calculate

⇒\sf{n = 1}

Hope I helped!

Best regards!!
