Answer 2

Answer:

pq=((x−1)+q)+ppq=((x-1)+q)+p

Step-by-step explanation:

Subtract From Both Sides

(pq−p−q+1)−1=x−1(pq-p-q+1)-1=x-1

Simplify Left Side

−p+pq−q=x−1-p+pq-q=x-1

Add To Both Sides

(−p+pq−q)+q=(x−1)+q(-p+pq-q)+q=(x-1)+q

Simplify Left Side

−p+pq=(x−1)+q-p+pq=(x-1)+q

Add To Both Sides

(−p+pq)+p=((x−1)+q)+p(-p+pq)+p=((x-1)+q)+p

Simplify Left Side

pq=((x−1)+q)+ppq=((x-1)+q)+p
