Wait, I'm confused. Can you write the question properly please and not in Latex. I don't get the second part so I can't help you.
+33661 T = number of T-shirts, P = number of pants
2T + 4P = 67.9 (1)
5T + 9P = 160.25 (2)
Multiply (1) by 5 and (2) by 2
10T + 20P = 5*67.9 (3)
10T + 18P = 2*160.25 (4)
Subtract (4) FROM (3)
2P = 5*67.9 - 2*160.25
Divide by 2
P = 2.5*67.9 - 160.25
Hence P = 9.5
Substitute this back into (1) or (2) and rearrange to find T.
