Answer: ?=126
Step-by-step explanation: Basically, 3 witches are equal to 45. We need to know how much one witch is. So, divide 45 by 3 to get 15 for one witch. 3 star wands are equal to 21, divide 21 by 3 to get 7 for one star wand. 3 brooms are equal to 12, divide 12 by 3 to get 4 for one broom.
Basically: One witch equals 15
One star wand equals 7
One broom equals 3
So, if we solve: 1 broom + 1 witch x 1 star wand we get 126.
3 + 15 x 7 =126
