Q&A - P5 Math

[BlueBells]

Hi elkniwt,


Thanks, but I still can’t understand it…probably needs some explanation by the side.

Question :
Why do we need to multiply by 2 and 3 respectively?

Thanks.

[Herbie]

it also can be written as


3u +9=3p - eqn 1
4u-18=2p - eqn 2

Try to make the p common
6u+18=6p
12u-54=6p

Hence 6u+18=12u-54

Thanks Herbie.


Now it all makes sense.
