Answer:
I don't think so.
Step-by-step explanation:
1/2p-(1/4p-4)
1/2p-(1-16p/4p)
(2p-1+16p)/4p
(18p-1)/4p
2(9p-1)/4p
9p-1/2p
First equation:
5(x+1)=20 —— distribute the 5 to the x and 1
5x+5=20 ——- subtract 5 from 20
5x=15 ———— divide by 5 from both sides
X=3 ————— answer
Second equation:
5x+1=20——— subtract 1 from 20
5x=19 ———— divide by 5 from both sides
X=19/5———— answer in fraction form
X=3.8————- answer in decimal form
