X=43

x+y^2=63

y^2=20

Y=2√5

2√5 x2z+43=53

4z√5=53-43

4z√5=10

Z=5/(2√5)

43+5/(2√5) x 2√5= 48

the answer is 48

solving the system of equations is the best way, I was too lazy and just made it straight with calculator) I think this puzzle is a great opportunity for people who answered wrong to learn some math right in this thread.

Helmet = 43

Assume that four pronged = 4 and five pronged = 5, then 43+4x5 = 63

Assume that XX means X squared rather than X+X (normal algebra states this)
...then 5*X*X + 43 = 53, so X*X = 2.

Finally 43 + SQRT(2)*5 is approximately = 50.071.

(As has been pointed out if XX means (X+X) then the solution is 48, but this is not normal schoolboy maths.)

43+43-43=43

43+4×5=63

5×2+43=53

43+1×5=48
