Algebra Puzzle (3 x 3)



First, we take the ice-cream as c.
The flower as w, and the gear as g.

Therefore,
15 = c + c + c
= 3c
c = 15 ÷ 3
= 5

Now that we know c = 5, the next step(3rd row) is:

35 = c + g + g
= 5 + g + g

Thus,

35 - 5 = g + g
30 = g + g
30 ÷ 2 = g
15 = g

Finally, we can evaluate(the 1st row):

c + w + g
=5 + 15 +w
=20 + w
=23

Therefore,

w = 23 - 20
= 3

So the answer is: Flower = 3
Gear = 15
Ice - cream = 5
