U would write the linear transformations as matrices, so it would be ([1 2] top half of 2x2 matrix, [3,4] bottom half) x T = (2x2 matrix with [-2 -3] top half and [-3 -11] bottom half)
Then to find T, u would multiply both sides from the left by the inverse of the bolded matrix, to end up with an equation like T = -1/2 (bolded matrix) x the last matrix, which u would equate

The results are more cuz nearly everyone does tutoring
Teachers are average, especially in yr 9 and 10

Gan is way too expensive

2x2: MGC, with CLL, global high 3s
3x3: RS3M, regular cfop, global 14.8s. I might get one of the tornado v3s soon tho
4x4: Meilong, yau, global 1:07
Square-1: Volt v2, vandenberg, global 19s
I also have a pyraminx and megaminx but I rarely practice
And ofc, square-1 is the best event
