The answer to this is p=-25/4 and in other ways it’s either p=-6.25, p=-6 1/4 or p=-5/2^2

Answer:


p=-6.25 or
p=\displaystyle-(25)/(4)

Explanation:


-160=22+8(3p-4)

Our goal here is to isolate p on one side of the equation. We will do this by performing inverse operations on both sides.

Subtract 22 from both sides:


-160-22=22+8(3p-4)-22\\-182=8(3p-4)

Divide both sides by 8:


-22.75=3p-4

Add 4 to both sides:


-22.75+4=3p-4+4\\-18.75=3p

Divide both sides by 3:


-6.25=p

You can also convert this into a fraction:


p=\displaystyle-(25)/(4)

I hope this helps!
