can you please explain:
p+qx =o
but how comes qx =-p?​

Answer 1

Answer:

see when we solve it the p goes on the right hand side

Step-by-step explanation:

p+qx=0

qx=0+p which is same as qx=p

Answer 2

Answer:

when something form left or right is moved to it's opposite side...the sign changes.. plus becomes minus..minus becomes plus..

and multiplication becomes division..and division becomes multiplication...
