Hi @johamilton Thank you for tagging me. This kind of puzzle certainly brings back memories of days gone by! My answer:

5 + 8 + 2 = 15

Hi @johamilton! Thanks for the tag and for organizing another fun contest! I love it! 😀

But I'll cross my fingers 🤞as I'm not much good in maths 🤣

15 (I guess)

5+8=13

8-2=6

5-2=3

5+8+2=15

Let 4-leaf clover = x, golden horseshoe = y, and St. Patrick's hat = z. This is a three-variable linear equation system. Thus, the equation is:

x + y =13 ...(1)

y - z = 6 ... (2)

x - z = 3 ... (3)

First, we need to transform the equation (2). z from the left side must be moved to the right side of the equation.

y - z = 6

y = 6 + z

y = z + 6 -> It forms a new equation, equation (4)

Second, substitute equation (4) to equation (1):

x + y = 13

x + z + 6 = 13

x + z = 13 - 6

x + z = 7 -> It forms a new equation, equation (5)

Third, eliminate z using equation (3) and (5)

x - z = 3

x + z = 7

------------- +

2x = 10

x = 10/2 = 5

x value found.

Fourth, find other unknown variable values using all defined equations.

We will pick equation (1) to find y value.

x + y = 13

5 + y = 13

y = 13 - 5 = 8

And we will pick equation (2) to find z value.

y - z = 6

8 - z = 6

z = 8 - 6 = 2

Now, substitute all values to the main problem:

x + y + z = 5 + 8 + 2 = 15

SOLVED!
