Answer:
Step-by-step explanation:
From equation 1 we can write ,
2q - r = 4p.................(1)
or, 2q - 4p = r ( side switched ) ................(2)
Now , 2p = r
or , 4p = 2r and we know 2r = q
Hence, we can write 4p = q ...............(3)
If we put equation (3) in (1)
we will get , 2q - q = r
or, q = r
q = r is proved
