Question

Enter the value of p that makes the equation

-- 3 = 2p - 9 true.
Sere
a) -3
b) 3
c) -6
d) 6
e) 12
f) -12

Answer 1

d) 6

Explanation:

`3=2p-9`

`2p-9=3` (Symmetric Property of Equality)

`2p-9+9=3+9` (Add
`9` to both sides of the equation to isolate
`p`)

`2p=12` (Simplify)

`(2p)/(2)=(12)/(2)` (Divide both sides of the equation by
`2` to get rid of
`p`'s coefficient)

`p=6` (Simplify)

Hope this helps!
