Step number 1: Rotate your monitor

Sri Lankan maths education is precisely engineered to make you hate maths.

I am sure @pdn.ac.lk will reply... But you should be able to work it out.

Note that...

So you are given (2, 3) trransforms to (5, 3). Write down the equations for this, you will get "a" from one of them.

Then find any point that lie on the line 2x + y = 12.
Transform this point as well. Now you are being told that the transformed point will have to lie on 2x - y = 12
So input the values of the transform you got to this equation. Then you will obtain b & c.

ya exactly, I have followed the same method explained by @imhotep

correction: 2nd equation --> b + 10 c = - 24

Sorry @pdn.ac.lk you made a mistake....with the negative sign. b + 10 c = -24
This gives a = 4, b = 6 and c = - 3.
Thanks for the working it out & scanning.

I thought, looking at my answers for b & c.

Romba thanks @imhotep @pdn.ac.lk ඇත්තමට මේ ප්‍රශ්නය දෙන පාඩම මොකද්ද කියල දන්නෙත් නෑ මාත් @Honda.putha

 

[TNHM]

මේ තියෙන්නේ matrix transformation ප්‍රශ්නයක් නේද ?
Youtube එකෙන් බලලා ඉගෙන ගත්තට මේ වගේ ප්‍රශ්නයක් ඇහුවම මොංගල් වෙනවා.
