X = 2y = 3z
Times 2, we get,
2x = 4y = 6z
Replace 2x and 4y in the original eq with 6z
1/6z + 1/6z + 1/4z = 4
Solving for z, we get
z = 7/48
Therefore, x = 3*(7/48) = 7/16

LCM of 2,4,8 is 8 it's square is 64 2^x = 64 then, x = 6 4^y = 64 then, y = 3 8^z = 64 z = 2 1/2 x + 1/4y + 1/4z =1/12 + 1/12 + 1/8 LCM of 12 and 8 is 24 =2/24 + 2/24 + 3/24 =7/24
