Answer:
Step-by-step explanation:
Let's do like-terms first which on the right side has the 2p:
17-2p=4p+5
Then make the variables on one side:
17=4p+2p+5
17=6p+5
Let's put that 5 on the other side:
17-5=6p
12=6p
Lastly, divide 6 to get a final remaining p.
12/6=p
2=p

=3
4x+−1=3
4x−1=3
Step 2: Add 1 to both sides.
4x−1+1=3+1
4x=4
Step 3: Divide both sides by 4.
4x
