The answer to this joke is hidden above. To find the answer, first, find what each of the expressions below equals when x = 3, y=5, and z =6. Then, find the letter that matches the code and write it on that line. Keep going until you can read the answer!

A: 2x + 4

B: 3y – 4

C: 2z + 3

D: x + 21

E: 11 – y

F: 5z

G: 2x + 1

H: x + y + z

I: 3y + 2z

J: 3x – z

K: 5x + y

L: 5y ÷ 5

M: 4x ÷ 6

N: 2x + 3y

O: 4z – 7

P: y + 3z

Q: 6z – 5

R: 4x + 7y

S: 1 + 2z

T: 6x + 4

U: 10y

V: 6z + 5

W: 8y + 6

X: 3(y + z)

Y: 2y – z

Z: 10x + 2

Because then it would be a foot.

A = 10, B = 11, C = 15, D = 24, E = 6, F = 30, G = 7, H = 14, I = 27, J = 3, K = 20, L= 5, M = 2, N = 21, O = 17, P = 23, Q = 31, R = 47, S = 13, T = 22, U = 50, V = 41, W = 46, X = 33, Y = 4, Z = 32
