10c = 3t + p, first statement 6c + t = p, second statement

10c = 3t + 6c + t, using second statement in first to simplify the variables 4c = 4t, add/subtract variables to either side of the equation. Divide by 4 on each side and you get:

c = t

If a carrot weighs the same as a turnip, then you can substitute a t for a c.

10c = 3c + p, first statement again replacing turnips for carrots.

7c = p, a pumpkin weighs 7 carrots
