Question

if p and q are two even positive numbers such that p-q is 420 and the sun of p and q is 920 then find the value of p and q​

Answer 1

Answer:

p = 670 , q= 250

Step-by-step explanation:

Given :

p-q = 420

p+q=920

add above 2 equations

we get-

p-q=420

p+q=920

____________

2p = 1340

p=1340/2

p=670

substitute value of p in equation 1 or 2 to find value of q

substitute in equation 1

p-q =420

670 - q = 420

q = 670 - 420

q = 250

p = 670 ,q =250
