Question

P+q equals 50 ,p-q equals 30,p*q equals what

Answer 1

Answer:400

Step-by-step explanation:

System equation p+q=50, p-q=30

p=40

q=10

p*q=400

Answer 2

Answer:

The value of pq is 400.

Step-by-step explanation:

Given:

p + q = 50...(i)

p - q = 30...(ii)

Solve both the equation simultaneously as follows:

p + q = 50

p - q = 30

________

2p = 80

p = 40

Substitute p = 40 in equation (i) and solve for q as follows:

p + q = 50

40 + q = 50

q = 50 - 40

q = 10

Compute the product of p and q s follows:

p × q = 40 × 10 = 400

Thus, the value of pq is 400.
