Dot sold 158 T-shirts and 107 shorts.

From the given information, we can write the following 2 equations.

x + y = 265

2x + 3y = 637

Multiply the top equation by 3 and use the elimination method to solve.

3x + 3y = 795

2x + 3y = 637

x = 158

If she sold 158 T-shirts, she must have sold 107 shorts.

265 - 158 = 107
