By arranging the equation

Explanation:

3p−1=5p−5−14+4p

after getting rid of parantheses.

Now collect p terms on the right-hand side and numbers on the other:

−1+5+14=5p+4p−3p

18=6p

186=p

3=p

The answer is p=3

p=3

Explanation:

3p−1=5(p−1)−2(7−2p)

3p−1=5p−5−14+4p, Removing bracelets.

3p−5p−4p=−5−14+1, bringing like terms together.

−6p=−18, simplifying.

p=−18−6=3

p=3

Explanation:

We can distribute the parenthesis on the right to get

3p−1=5p−5+4p−14

We can combine our like terms on the right to get

3p−1=9p−19

Next, let's add 1 to both sides to get

3p=9p−18

Next, do get our variables on one side, let's subtract 9p from both sides to get

−6p=−18

Lastly, we can divide both sides by −6 to get

p=3

Hope this helps!
