Question

7p − p = 18 2) −5n − 4n = −9

Answer 1

Answer:

$\boxed{ \bold{ \sf{ \boxed{ p = 3}}}}$

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

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!

Answer 2

Answer: p = 3 , n = 1
Step by step explanation
7p-p = 18
6p = 18
p = 3
Finding n
-5n-4n = (-9)
-9n = (-9)
n = -9/-9
n = 1
