Solve for p and q if
p+q=2(p-q)
pq=675

Step-by-step explanation:-

Let p + q = 2( p - q) be eqn.1 and pq = 675 be eqn.2

Now , lets expand eqn.1

Lets put the value of p in eqn.2

Lets find out the value of p.

When q = +15 ,

When q = -15 ,

Hence ,

p = ±45

q = ±15

q=15

p=45

Step-by-step explanation:

p+q=2(p-q)

p+q=2p-2q

simplify: add 2q to each side and subtract one p from each side of the equation.

p=3q

given that pq=675, substitute:

(3q)q=675

3q^2=675

q^2=225

q=15

then p=3q or p=3(15)=45

p=45
