Question

7p − p = 18 2) −5n − 4n = −9

Answer 1

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

Answer 2

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

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

Explanation:

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

Collect like terms

⇒
`\sf{6p = 18}`

Divide both sides of the equation by 6

⇒
`\sf{ (6p)/(6) = (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{ ( - 9n)/( - 9) = ( - 9)/( - 9) }`

Calculate

⇒
`\sf{n = 1}`

Hope I helped!
